Method for preparing (co)polymers having a narrow molecular weight distribution |
摘要 |
The present invention concerns a novel method for preparing polymers (preferably (meth)acrylate polymers and copolymers) having a narrow molecular weight distribution by metal-free anionic polymerization in the presence of a phosphonium salt of a nitrogen, oxygen and/or sulfur anion. The present invention also concerns block copolymer and methods of making the same using anionic polymerization in the presence of the phosphonium salt to prepare at least one block of the copolymer.
