BIODEGRADABLE ELASTOMERS PREPARED BY THE CONDENSATION OF AN ORGANIC DI-, TRI- OR TETRA-CARBOXYLIC ACID AND AN ORGANIC DIOL

摘要

The present disclosure relates to biodegradable and biocompatible elastomeric polymers prepared by the condensation of an organic di-, tri- or tetra-carboxylic acid and an organic diol followed by thermal crosslinking with a bis- or tri- lactone or reaction with a photosensitive compound and subsequent photocrosslinking. Said elastomers are amorphous, have a glass transition temperature below both room temperature and body temperature and will homogeneously degrade to water soluble by-products with no reported toxicity.
