Filed:

Apr 21, 2008
Appl. No.:

12/594608
Inventors:

Walter Skalla - Old Lyme CT, US
Allison Calabrese - Memphis TN, US
Ahmad R. Hadba - Middlefield CT, US
Nadya Belcheva - Hamden CT, US
International Classification:

C08G 18/70
C08G 18/36
C08G 63/00
C08G 59/00
US Classification:

528 67, 528 83, 528272, 528365
Abstract:

Methods for producing biocompatible compositions are provided. The biocompatible compositions include an aliphatic polyester macromer produced without the use of solvents or catalysts. The resulting aliphatic polyester macromer may be reacted with a polyisocyanate to form an end-capped aliphatic polyester macromer which, in turn, may be reacted with a polyol to produce a polyurethane. The polyurethane, in turn, may be reacted with a second polyisocyanate to produce an isocyanate-functional polyurethane. The compositions prepared by the methods of the present disclosure may be used as adhesives or sealants for medical/surgical uses.
