摘要

2098713 9212189 PCTABS00014 A biocompatible mouldable curable polymer/monomer system is provided which is capable of curing at ambient temperatures to provide an elastomer product while producing a lower exotherm than previously used systems. The system comprises (a) an alkyl acrylate or methacrylate homopolymer or copolymer, (b) a monomer mixture of a higher alkyl acrylate or methacrylate combined with one or more of acrylic acid, methacrylic acid and their lower alkyl esters and (c) a plasticizer. Cross-linking agents, anti-tack agents, and activators or photoinitiators are preferably included. Particular uses include preparation of doughs for use in producing earmoulds and earpieces or in fabrication of prostheses.
