PROCESS FOR THE POST-MODIFICATION OF HOMO AND COPOLYMERS PREPARED BY CONTROLLED FREE RADICAL POLYMERIZATION PROCESSES |
摘要 |
The instant invention pertains to the preparation of polymers or copolymers wherein in a first step a controlled free radical polymerization process is carried out and in a second step the resulting polymer is modified by transesterification reactions. The final modified polymer or copolymer is useful as a dispersant for pigments. Further aspects of the invention are the thus prepared polymers or copolymers, a pigment concentrate containing the polymer or copolymer and a coating material containing the pigment concentrate. |
