Abstract：Terpolymers of DLLA/GA/TMC with different molar ratio were synthesized and used in the preparation of absorbable membrane,the membranes could be guided bone regeneration (GBR).These copolymers were characterized by H-NMR and GPC.By DSC, XRD and tensile test,the effects of molar ratio on the copolymer and GBR membrane thermal properties, mechanical properties and crystallization properties were studied.We find that the copolymer and GBR membrane glass transition temperature and the tensile strength increases with TMC content show a trend of decrease, crystalline and elongation at break increased with the increase of content of TMC presented.The GBR membrane which TMC content is 25% is expected to be used for the animal and clinical trials.
