POLYMER, PROCESS AND COMPOSITION |
摘要 |
There is described a method of preparing a post-modified polymer the method comprising the steps of: (1) polymerising a monomer composition comprising from 2.5 to 75% by weight of the total monomer composition of at least one itaconic anhydride, precursor thereof and/or derivative thereof in a polymerisation method to obtain an itaconate Polymer A; (2) reacting in a post modification step at least 10 mole-% of the anhydride groups, anhydride precursor groups and/or anhydride derived groups of the Polymer A obtained from step (1) with a Nucleophile B to form a post-modified Polymer C, and optionally using said polymer C as seed or stabiliser in a further step (3) to form a sequential Polymer D. |
