Claim 1
Independent Claim
64 words
BACTERIOSTATIC COMPOSITIONS OF MATTER, THE ESSENTIAL CONSTITUENTS OF WHICH ARE (1) A FIBER-FORMING ACRYLONITRILE POLYMER, WHICH POLYMER CONTAINS IN THE POLYMER MOLECULE AT LEAST 85 WEIGHT PERCENT OF ACRYLONITRILE, ANY BALANCE BEING ANOTHER MONOETHYLENICALLY UNSATURATED MONOMERIC MATERIAL THAT IS COPOLYMERIZABLE WITH ACRYLONITRILE, AND (2) DISPERSED THEREIN BETWEEN ABOUT 0.5 TO 20 WEIGHT PERCENT, BASED ON THE WEIGHT OF SAID FIBER-FORMING ACRYLONITRILE POLYMER, OF 2,2''-THIOBIS(4,5-DICHLOROPHENOL).
