| 摘要 |
The present invention relates to a polymeric binder composition comprised of two polymeric components wherein one of the two polymeric components is a lightly cross-linked copolymer comprising, in polymerized form, an alpha , beta -ethylenically unsaturated carboxylic acid, an ester of an alpha , beta -ethylenically unsaturated carboxylic acid and an unsaturated nitrile. In general, such cross-linking is achieved using a small amount of a cross-linking monomer such as allyl methacrylate.
