Abstract:
A hydrogel-forming system which comprises from 0.01 to 99.99% by weight of (A) a hydrophobic macromer with unsaturated group terminated ends which is prepared by reacting the hydroxyls of a diol obtained by converting hydroxy of terminal carboxylic acid group of aliphatic polyester to aminoethanol group, with an unsaturated group introducing compound, and from 99.99 to 0.01% by weight of (B) a hydrophilic polymer which is a polysaccharide containing hydroxy groups which are reacted with unsaturated group introducing compound; wherein (A) and (B) constitute different compounds from one another and the total of the percentages of(A) and (B) is 100%.
