Process for polymerizing a composition in the presence of a block copolymer
Abstract
A method for polymg. a compn. in the presence of at least one block copolymer used to make polymers with controllable morphol., esp. a specific ratios of soft to hard segments in polymer mol. comprises mixing ≥1 macroinitiator, ≥1 block copolymer and a soln. comprising ≥1 monomers, polymg. the soln. by ATRP, RAFT, ROTP or nitroxide mediated polymn. and removing the formed polymer. Thus, 3,7-dioxa-4-aza-6-phosphanonanoic acid, 4,5-bis(1,1-dimethylethyl)-6-ethoxy-2,2-dimethyl-, 1,4-butanediyl ester 6,6'-dioxide prepd. by reacting monoalkoxyamine 3,7-dioxa-4-aza-6-phosphanonanoic acid, 4,5-bis(1,1-dimethylethyl)-6-ethoxy-2,2-dimethyl-, 6-oxide with 1,4-butanediol diacrylate was used for manufg. Me methacrylate - Bu acrylate diblock copolymer.
