Resum
Copolyesters from 1,4-butanediol, dimethyl terephthalate and either 2,3:4,5-di-O-methylene-galactitol or dimethyl 2,3:4,5-di-O-methylene-galactarate with compositions of 10, 20, 30, 40 and 50% of either galactitol or galactarate units were prepared by melt-polycondensation. The copolyesters had Mw in the 32,000–41,000 g mol-1 range and had a random microstructure. They displayed Tg from 20 to 70 °C with values steadily decreasing with the content in galactarate units but increasing with the c...
