| abstract | PCT No. PCT/EP93/02426 Sec. 371 Date Apr. 26, 1995 Sec. 102(e) Date Apr. 26, 1995 PCT Filed Sep. 7, 1993 PCT Pub. No. WO94/06269 PCT Pub. Date Mar. 17, 1994 <IMAGE> (I) The invention relates to a process for (co)polymerizing vinyl monomers in the presence of a radical polymerization initiator, characterized in that said radical polymerization initiator is a 3-methylpentyl-3-peroxy alkanoate of formula (I) wherein R1, R2 and R3 represent alkyl groups each having at most 9 carbon atoms with the proviso that the total number of carbon atoms of R1, R2 and R3 is at most 11, said 3-methylpentyl-3-peroxy alkanoate being employed in an amount of 0.002 to 2.0 parts by weight, based on 100 parts by weight of monomers present, said process being carried out at a temperature above 20 DEG C. The use of 3-methylpentyl-3-peroxy alkanoates in the present invention surprisingly and unexpectedly results in a higher polymerization velocity, a shortened polymerization time, and an increase in conversion as compared with the results obtained by using other radical polymerization initiators. It has also been found that the obtained polymer has excellent thermal stability and is not affected by odour or coloration. Thus the industrial value of the radical polymerization initiator peroxide of the present invention is remarkably high. |
