Peroxided polymers - for making graft or sequenced copolymers of controlled structure

摘要

Peroxidized polymers are made by deactivating a living or metallized polymer pref. obtd. by anionic methods, by >=1 org. cpd. having >=1 peroxide gp. One or both O atoms of the peroxide gp. are pref. linked to an alkyl, aryl or arylalkyl gp. which may be linked through a CO gp., and which pref. have >=1 reactive gp. or a halogen atom. Graft or sequenced polymers are made by polymerizing >=1 monomer with >=1 peroxidized polymer.
