THERMOSETTING COMPOSITION CONTAINING EPOXY FUNCTIONAL POLYMER AND CARBOXYLIC ACID FUNCTIONAL POLYMER PREPARED BY ATOM TRANSFER RADICAL POLYMERIZATION |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To develop a new improved epoxy-acid curable powder coating composition having a combination of substantially zero VOC level and desirable performance characteristics. <P>SOLUTION: This thermosetting composition contains a particulate mixture of coreactive solids comprising (a) a polycarboxylic acid functional polymer and (b) an epoxy functional polymer. The polycarboxylic acid functional polymer and epoxy functional polymer are each prepared by atom transfer radical polymerization and each has a sufficiently regulated polymer chain structure and a polydispersity index below 2.5. The composition is useful as a powder coating composition. <P>COPYRIGHT: (C)2004,JPO</p> |
