| 摘要 |
<p>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 polymerisation in the presence of a phosphonium cation. The present invention also concerns block copolymers and methods of making the same using anionic polymerisation in the presence of a phosphonium cation to prepare at least one block of the copolymer.</p> |
