Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
108 words
A HOMOGENEOUS BLEND OF FROM 1 TO 99 PARTS OF A LINEAR POLYMERIC CARBONAMIDE WHICH CONTAINS RECURRIN CARBONAMIDE GROUPS AS IN INTEGRAL PART OF THE POLYMER CHAIN, SAID CARBONAMIDE GROUPS BEING SEPARATED BY AT LEAST TWO CARBON ATOMS, AND FROM 99 TO 1 PARTS OF A SUBSTANTIALLY LINEAR SYNTHETIC COPOLYMER CONTAINING FROM 98 TO 50 PARTS BY WEIGHT OF A NEUTRAL MONOMER WHOSE POLYMER IS NORMALLY SUBSTANTIALLY INCOMPATIBLE WITH SAID LINEAR POLYMERIC CARBONAMIDE AND FROM 2 TO 50 PARTS BY WEIGHT OF AN A,B-ETHYLENICALLY UNSATURATED CARBOXYLIC ACID, SAID NEUTRAL MONOMER BEING SELECTED FROM THE GROUP CONSISTING OF BUTADIENE-1,3, VINYL CHLORIDE AND A MIXTURRE OF BUTADIENE-1,3 AND METHYL METHACRYLATE.
