High activity organic peroxide polymerisation initiator mixt. - of di:acyl peroxide(s) of aliphatic acids, have reduced explosion hazard

摘要

Peroxide mixt. is based on 2-8 pts. wt. diacylperoxides of aliphatic 3-5C aliphatic acids, 80-89 pts. wt. diacyl peroxides of 6-9C aliphatic acids and 7-14 pts. wt. diacyl peroxides of aliphatic 10-12C acids. The peroxide mixts. have a high initiation activity in radical polymerisation processes for unsatd. monomers. They are less of an explosive risk than prior art peroxide mixts., so that less desensitising liq. can be used, and the amt. of extractable material in the resulting polymer is reduced.
