Novel branched blockcopolymers from poly(vinylpyridine) by chromium allyl compounds

摘要

Novel branched blockcopolymers from polyvinylpyridine are formed by chromium allyl compounds. Our present work shows results for the homopolymerization of vinylpiridine (VP), dimethylacrylamide (DMAA), tert - butylacrylate (t - BA) as well as the graftcopolymerization of poly(vinylpyridine) (PVP), using tris (pi - allyl) chromium (TPC) as initiator. PVP activated by TPC was used for grafting with DMAA - "grafting from". On the other hand living PDMAA polymerized by TPC, was able to react with PVP chain - "grafting onto". [References: 10]
