摘要
Polyalkylenepolyamines and gelatins are crosslinked in a non-anhydrous anvironment to yield water-swellable, essentially water-insoluble gels and foams. The polyalkylenepolyamine is contacted with a polyisocyanate at a pH between 5 and 8 and subjected to a high rate of agitation. The gelatin is contacted with a polyisocyanate at a pH between 6 and 8 and subjected to a high rate of agitation. The process of this invention can be employed to immobilize proteins, enzymes, antibodies, etc.
