| 摘要 |
This invention provides a novel phosphatized polymeric product which is formed by: (a) forming an amine-extended resinous composition having unreacted epoxy groups by mixing, under free-radical initiated polymerization conditions, a polymerizable, ethylenically unsaturated monomeric component and a polyepoxide component; and (b) phosphatizing at least a portion of the unreacted epoxy groups of the resinous composition. The present invention also provides novel coating compositions containing the aforedescribed polymeric product. While these novel coating compositions have a number of different uses, they are particularly useful for application to metal substrates such as can end stock since they result in a cured film which has excellent performance properties such as flexibility and extensibility, adhesion, resistance to boiling liquid pack tests and boiling water taste test results. |
