Abstract：A series of Poly(butylene carbonate-co-tricyclodecane dimethanol carbonate)(PBTCx, x is the percentage of TCD in the total diol in the feed) were synthesized from 1,4-butanediol, 4,8-bis(hydroxymethyl)tricyclo[184.108.40.206(2,6)]decane and diphenyl carbonate by two-step method of melting transesterification and polycondensation. The microstructure and composition of PBTCs were characterized by 1H NMR and 13C NMR. The molecular weight, glass transition temperature(Tg) and thermal stability of PBTCs were researched by GPC, DSC, XRD and TG. The results showed that the Mw of PBTCs was 10500~124800 g?mol-1, the Mn was 6300~73000 g?mol-1, and the PDI was 1.59~1.73; PBTCs showed amorphous morphology and Tg was -3.43~70.90 ℃. PBTCs showed higher thermal stability than PBC. The results of film tensile test show that PBTC30(tensile strength 33.54 MPa, breaking elongation 275.69%) and PBTC40(tensile strength 32.13 MPa, breaking elongation 294.63%) have higher strength and toughness, and have certain application potential in film materials.
