ABSTRACT:
Method for forming a polyurethane based adhesive composition in which a reaction mixture of at least one NCO-terminated prepolymer and a polyhydroxy compound is heated at a temperature and for a length of time sufficient to provide a gel content of from about 30 to 42% by weight and a molecular weight of extractables of at least about 45,000. Polyurethane based adhesives prepared by the method and medical devices employing the same are also disclosed.
