Patent ID: 8598053

Claim:
A composition of matter comprising a fibrous material having poly(phenylene ethynylene)-based cationic conjugated polyelectrolyes bonded thereto, the composition being prepared by contacting a fibrous material comprising a fiber-forming polymer having iodophenyl groups bonded thereto and a di-iodo reagent of formula (2) wherein R 1 is a DABCO group of formula wherein X is an anion and a wavy line indicates a point of bonding and a phenyl-diyne reagent of formula (3) in the presence of a catalyst comprising palladium(0) and CuI under conditions suitable to provide the fiber-forming polymer having the poly(phenylene ethynylene)-based cationic conjugated polyelectrolyte covalently bonded thereto, the fibrous material comprising the fiber-forming polymer exhibiting biocidal activity.
