PHOTOPOLYMERISABLE MATERIALS FOR USE IN WOUND DRESSING

摘要

A composition that is photopolymerisable in the presence of water comprising: (b) a first water-soluble monomer having olefinic unsaturation and a flexible hydrophilic chain; (b) from 0.2 to 20 parts by weight, based on the weight of the first monomer, of a second water soluble monomer having olefinic unsaturation and a group that imparts tackiness on curing, and which is of high free radical polymerisation efficiency; (c) from 0.001 to 0.5 parts by weight, based on the weight of the first monomer, of a cross-linking agent; (d) from 0.001 to 0.5 parts by weight, based on the weight of the first monomer, of a photoinitiator; and (e) from greater than 20 % up to 50 % by weight, based on the total weight of the composition, of a low molecular weight polyol.
