In the present paper the authors,inte~nded to study the oinetios of 293 DMB-2 and'of related eompo-ands at high pressure and to investigate the properties of the poly-mers. This reaction takes place gradually under a pressure of'3660-36ao atm and at.a temperature of 290-29200 an'l passes through a dimer state (which has its maximum yield after about 16 hrs).,The-dimer fraction is able to undergo further polymerization. The degree of polymerization after 32 hrs is still low (9,1-17,7%)- Unaer the same conditions 2,3-DMB-i and 3#3-DhW-1 are polyzerzated CARD 1/3 PA 2917 The polymerization of 2,3-Dimethylbutobe-2$'2y3-Dinethilbutene-I and 30-Dimethylbutene-1 at pressures iip t0,4#000 atx4i~ much faster and form products of a high molecular weight. The polymers of the threo'hexanes undei discussionp which are similar with respect to their molecular ireight, show considerable- differences among themselves and with regard to the products of ion polymerization. Since the present of 2,3:DMB-1 was established -in the monomer fraction of the polymeriBation product 2P 3 DMB-2, the authors carried out polymerization expeirimants with a . mixture of both substances, If they *e'r6 mixed with a ratio of 1 : 1, 293--DMB-2 reacted much faster than 20,40-1 in comparison to separate polymerization of either hexane. In the case of~ 'small admixtures of the latter hexane to the former these effe'otsiare not observed. This is indicative of a co-polynerization.; a fact, which is confirmed by the values of theAlffraction coefficient and by the specific weight. No formation talkee place, %herefore, of a simple mixture of the polymers of both hexanes. Consequent- ly the polymerization of 293-DIO-2 does not pass throu8h a preceding stage of isomerization of the From the ~investigation of the aimer fraction, vfhich consists at least of CARD 2/3 PA - 2917 The polymerization of 2,3-Dinathylbutene-2,, 2,3-Dimethyl- butens-1 and 30-Dimethylbutene-1 at Pressitres up to 4.000 atm. two olefines, it appears that, in the case ofthe-polymerization of the three hexames underloonsideratioh, as etructural:poly- merization takes place. Without this procens'.the formation of Cis-dalkylethylenes could not be expecied. They predominate, however, in the dimer fraction. Moreover, the formation'of nono- alkylethylenes would not be imaginable without the assumption that in the case of the polymerization of 20 DMB-2 it is not the molecules or the radicals of the monomeres that are'aubjekt to a structural isomero2ation, but dimer molecules or the radicals C H Results show that the reaction of thermal 12 23- polymerization accelerated by pressure.is slowest in the oas 'e CARD 3/3 of 4-subBtituted ethylenes.

Based on the comparisons of the properties and.the structure of dimer fractions of the polymerization pr.o~ducts of[ 2,3-dimethyl butene-2 and 2,3-dimethyl butene-1 it is assumed that the polymerization of 2,3-dimethyl'butene-2 takes placemainly not by way of:,tho stage of the preliminary isomerization in 20-diaeifi~l. butenet-10 From the data obtained on the s~juc,ture of dime~r,fractions it may be concluded that under~the conditions in- vestigated besides the displacement of the double bond also a structural isomerizatio-n*(al 'iparently ofthedimer molecules or radicals C H ) t4ke;3 place.

This article gives the results of an investigation of polymerization of acrylonitrile in a solution of dim ethyliorm amid e init" t d by dinitrile of azoisobutyric acid at atmospheric pressure and at Z000 kg/CM2-.

The authors explain the cori,-Wratively small increase of molecular weight at 2000 kg/cmZ by the fact that in the studied system an appreciable role is played by the reaction of chain transfer through dimethyl-' formamide and this reaction is accelerated by pressure almost to the same extent as the reaction of chain growth.

Radical polymerization of styrenes initiated with azoisobutyrodinitrilesi was studied at pressures up to 2000 kg/~2 in benzenes butyrall ydes-and tH irl mix- tures at 500C.
