TITLE Acoustic Double Refraction of Phonyl-Ethyl Alcohol at Low Temperatures kAbistichaskoye dvoynoye luchaproloialaniya fenil-atilovogo spirta pri nizkikh tomporaturakh) PERIODICAL: Optika i Spektroskopiya, 1959, Vol 6, Nr 5, pp 616-619 (USSR) ABSTRACT- The authors measured viscosity and acoustic double refraction of phonyl- ethyl alcohol (C6H502020H). Viscosity was measured between +20 and -37-50C by the falling sphere method. Viscosity increases in this region of temperatures from 0.115 to 56.8 poises. Acoustic double refraction was measured by a method described earlier by Tavatkov and Eakin (Refs 3, 6) at ultrasonic frequencies of 18.8 and 38.6 Mc/s at five temperaturest -29.5. -33.0, -34.0, -36.0, -37.50c. Trio quantity measured in acoustic double-refraction studies was dwhich it; the angle of rotation of the analysar in the polarization photometer. The angle oL, plotted as a funation'Nol tags V applied to the electrodes of the A vibrating quartz plate, is shown in a figure on p 617 for temperatures of -37.5 0 and -29.50C. Benzine was used as the working liquid in which the quartz ultrasonic source and a small cell containing a card 1/3 millimetre thick layer of phenyl-athyl alcohol were placed. Tne whole SOV/51-6-5-9/34 A~ouatic Double Refraction of Phonyl-Ethyl Alcohol at Law Temperatures apparatus was thermally insulated and temperature was measured with a pentane thermometer. The acousti: double-refraction coefficient K in given by 'K = bc~ot/fw?,EmV, where b = (v~/_6.4) x 108; c is the velocity of sound in phanyl-athyl alcoh 1 X I th~ wavelength of the light used in double refraction 0 :nts Jam, y 5500 1); experim 1 t is the path of the light beam in the ultrasonic field (t = cm); w is the frequency of ultrasonic vibrations- is the viscosity of the liquid; m is the ratio of the acoustic ;~palsvacss of quartz and bantine (m = 10); oL is in radians and V is in e.s.u. units. The values of K are given in cola 3 and 4 of Table 1 for 18.8 and 38.5 Mcls respectively. 'Xhosa valuea are all of the order of 10-11. The relaxation time of molecular crientation T In phenyl- ethyl alcohol was calculated from 2 1 T = 1 "-1 2 9 _W C72 where 9 is the dynamic double-refraction coefficient. The values of 'r arc given in cola 3 and 4 of Table 2 for 16.8 and 38.5 Mc/s respective7y. Card 2/3 SOV/51-6-5-9/34 -Acoustic Double Refraction of Phonyl-Ethyl Alcohol at Low Temperatures These values range from 1.0 to 2.1 x 10-7860. Errors in determinatien of t were introduced because the quartz oscillator was tuned visually and, therefore, inaccurately. Determination of r by a different method showed that the values of the relaxation time deduced using Eq (6) were too high by a factor of 2-4. It follows that, at -37 500, we should take 'C = 5 x 10-8sec, instead of the mean value of 1:7 x 10-7g9c given in 'fable 2. The lower values of % agree with those calculated from the dynamic double -refraction coefficient M and the data obtLined by measurement of depolarization of light scattered in phenyl-ethyl alcokol.

The dimension determination of macro- molecules with molecular weights ranging from 104 to jo5, is of special interest, since in this range the transition takes place from solidt weakly bent, rod-shaped molecules to statically coiled molecules not traversed by the solvent. The author found the asymmetry of the critical opalescence in the system polystyrene - cyclohexane (Ref. 6). Former results (Refs. 6,7) obtained by measuring the asymmetry of the critical opalescence in solutions of very narrow fractions of polystyrene in Card 1/3 Asymmetry of the Critical!Opalescence in Solutions of Poly~tyrene in Cyclohexane 87026 S/190J60/002/007/008/017 B020/BO52 cyclohexane, are interpreted in the present paper. The scattering asym- metry was measured by a photoelectric nephelometer (Ref. 8) at angles ranging from 25 to 1500- Cuvette and thermostat are described in Refe 9. A common TC-15 (TB-15) circulation thermostat was used for thermostating. The wavelength of the light used# was 5460 A. The photoelectric nephelo- meter for determining the molecular weight was the same as above.

The optical anisotropy of the copolymer was determined by flow birefringence in bromoform. According to W. Kuhn and H.

The experimental value, which is four times as high, is explained by the fact that the chain stiffness of the graft copolymer is higher than that of homopolymers.

Doklady, v. 165, no. 3, 1965p 623-625 TOPIC TAGS: polymer physical chemistry, intermolecular force ABSTRACT: Debye proposed a method (J. Chem Phys. p 319 680, 1959) for the determination of the mean radius I of the action of intramoleoular forces in polymer solutions based on the measured asymmetries of the critical opalesc eace. According to the same author (P. Debye et al. , J. Chem. Phys. f 30', 1803, 1962), the quantity 12 depends on the mean square radius TR2 of the Inertia of polymeric coils within the iiolution (at critical concentration and near the critical temperature Tk) and on the cohesion eiiergy density for the polYmer-P-olymer (8 22), solvent-solvent (9 11), and polymer-solvent ($; 12) combinations. Since 12, R2, and 8 11 may be determined separately, they can be used for the determination Of 9 22 and S 12 - The present authors carried out the determination 4 the molar energy of cohesiOnj' 22 V2, and the results are onymmarized In Table 1. 1/3 UDC: 678. 01:53 + 541. & jkCC NRt APS028914 TABLE I - Energy of cohesion of R2jyz8-vInXInaphtaleneI PolvmphtvImghpa~clat&j and polybutyboethaorylate.

Two additionit , criteria were used: there should be no proton among the a-econdary :;.tracks of the "primary'ster" and in one-prong interactions where the, observed track is a proton' also its angle wit 'h the line of flight of the "neutral particle" should be compatible with the kinematics of an n-p collision.
