PREPOLYMER FOR BIOMEDICAL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a prepolymer for a biomedical material which can be changed in number of molecular groups to modulate the air-permeation, oxygen-permeation and humidification and improve the compatibility with the other hydrophilic molecule.

SOLUTION: The prepolymer is represented by chemical formula (1) [wherein X1 is an aliphatic compound or an aromatic compound; X3 is an olefin functional group-containing compound; and X2 is a siloxane compound having a chemical formula (2)].
