MAMUFACTURING METHOD OF PRECURSOR FOR THERMOSET SHAPE MEMORY ELASTOMER MAMUFACTURING METHOD OF THERMOSET SHAPE MEMORY ELASTOMER USING THE PRECURSOR AND THERMOSET SHAPE MEMORY ELASTOMER

摘要

The present invention relates to a method for preparing a precursor through a simple synthesis process, a method for preparing a thermosetting shape-memory elastomer which has controllable mechanical properties and is stable against heat, and an elastomer. The method for preparing a precursor for a thermosetting shape-memory elastomer includes the steps of: (a) synthesizing hydroxyl-telechelic poly(carvomenthide) ((-PCM-OH)_2) through ring-opening transesterification polymerization (ROTEP) of carvomenthide; (b) copolymerizing the hydroxyl-telechelic poly(carvomenthide) with D,L-lactide to obtain hydroxyl-telechelic poly(carvomenthide)-poly(carvomenthide)-poly(lactide) block copolymer (-(PCM-PLA-OH)_2); and (c) esterifying the hydroxyl-telechelic poly(carvomenthide)-poly(carvomenthide)-poly(lactide) block copolymer to obtain carboxy-telechelic poly(lactide)-poly(carvomenthide)-poly(lactide) block copolymer ((-PCM-PLA-COOH)_2) represented by the following Chemical Formula 1.
