The authors of the present paper wanted to synthe3iZ9 mixed pcly- amides by means of non-.equilibrium polycondensation in "he interface, and to study the influence exerted by the reactivity of the ini t iaj substances on the composition of the polyamides.

Izvestiya. 0 tdeleniye khimicheakikh- nauk, no. 11, 1962, 2o62 - 2o69 TEXT. The rules governing the interfacial polycondensation of adipyl chloride (AC) with a mixture of ethylene diamine (I) and m-phenylene diamine (II), or I and hexamethylene diamine (III), were studied. Poly- amides were also synthesized from sebacyl.chloiide (SC) and a mixture of III and piperazine (IV). The polycondensation-was carried out at room temperature; the chloride wan dissolved in'benzene, the diamines in aqueous alkali. The molar ratio of the diamines was varied between 0:1 and ItO. The relative reaction rate of I! and III was determined by acylating their .mixture with benzoyl chloride. The nitrogen content of the reaction prod- uct and its IR spectrum proved that mainly,dibenzoy~_hexamethylene amine was formed and that the reaation rate of III was consequently much higher Card 1/3 S/062/62/000/011/012/021 Heterochain polyamides ... B100144 than that of II. In the polyoondensation of AC with diamines the following were determineds the initial ratio K 1 of the diamines, the ratio K 2 of the diamines in the copolymer, and a - K2/K1 . The following values were found: K 1 . I/Ii K2 . I/II K1 - I/III K2 .

After prolonged polycondensation of AC with I and II, the I content in the polymer increased owing to exhaustion of the diamine mixture with respect to II, which had the principal share in the early reaction stage. The system of SC behaved similarly with III and IV. These results are explained by the different rates of diffusion of Card 2/3 B/062/62/000/011/012/p2l Heterochain polyamides... B101/B144 the diamines into the organic phase. It is (in m/cm 2. min) 3.9-10-7 for 1, 6.07-10- 5 for II, and 1.07-10-5 for III. The dissociation constants are 8-5-10- 5, 6.o.lo- 10 , and 5.1-10-4, respectively. In the polymt:-, the con- tent of radicals of the diamine primarily depends on the rate of diffusion. The reactivity is of secondary importance and has a compensating effect on the polymer composition if the slowly diffusing diamine has a higher reac- tion rate (dissociation constant).

Synthesis of polyamide esters by interfacial polycdndensation PERIODICAL: Vysokomolekulyarnyye soyedineniya, V. 4, no. 10, 1962, 1457-1462 TMT; A comparison is made between the properties of polycondensateD obtained by interfacial polycondensetion (iC)- and equilibrium poly- condensation (eC) of sebacic chloride (1), diane(4,4f-dihydroxy-diphenyl propane) (II), and hexamethylene diamine (III). Interfacial polycondensa- tion was achieved by mixing 0.2 1''.1 alkaline solutions of II and III -With I dissolved in hexane, and eC was brought about by heating the component mixture first in N and then in vacuo, the ratio I II : III being varied 2 between 1 : I : 0 and 1 : 0 : 1. Homopolymers could be separated from the reaction product since the homopolymer I + III is insoluble in Card 1/3 S/19 02/004/010/001/GIO Heteroc*hain -pblymer3 -XL.'

Conclusion: I diffuses from the organi*&-into the aqueous phase owing tohydrolysis duri,ng iC; III diffuses into the organic phase more readily than II. Hence, the polymer formed from the or~;anic phase should contain amide units, and the product formed from the aqueous phase and should be enriched with ester units. ~,This was confirmed by iC when the mixture was stirred at varying speeds.~~At a ratio of 6 : 5 :.1 and at 1000 rpm, the Card 2/3 Ileterochain polymers.

The generalization of the most reliable data by A. Soiff (NACA TN 3248, 1954) confimed the modified Reynolds analogy Ch However, due to insufficient amount of experimental data and poor accuracy Card 1/2 L 20136-63 ACCESSION NR: AP3004804 Seiff was unable to establish a realtion between Ch/Cfand the Reynolds number, 11-lach nuznber, and'the tenperature factor. The present paper#' on the basis of ex-oeriments described by V. S. Avduyovskiy et al. (03novy* toploperedachi v avi- atsionnoy i reketnoy tekhnike, Oborongiz, 1960). establishes the relationship GhW I where G/. 2 pW (D, T, / T), (1.3) 01 (I?xw.

Such geostructural eleme in the west are the Belorussian Massif and the adjacent Brest and sub-11altic depressions, and in the east the Moscow and Pripyat' basins. In determining location of wells within the individual hydrogeological regions, hydrodynamic,'W hydrochemical, geothermal, and gas characteristics of the different abyssal layers were taken into account.

A thin byA reactive-diffusion ptocess formed ajunction with Se.- A voltage ~)f 30-35 v was, applied. to the specimen, :and a steel probe was set at 1; Is from the junction. Potential-distribution,curves were measured. It was found that. 1) the, space-charge'o at a distance of 4 11 from the junction 15 practically nil; 2) the reactive-diffusior'i-,-_ produced contact is, in fact,:a. defective-hetero-p-n Aunction (conducting channels be found in the junction); and 3 t i-e nonuniformity of the D-n junction can be "t J ca i/2
