| abstract |
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 a, β-ethylenically unsaturated carboxylic acid, an ester of an α,β-ethylenically unsaturated carboxylic acid and an unsaturated nitrile. In general, such cross-linking is achieved using a small amount of a cross-linking such as allyl methacrylate. |
