Crystalline polyester resins and process for their preparation |
摘要 |
A moldable linear polyester resin consisting essentially of a polyester having the formula: where R is an alkyl from 1 to 6 carbon atoms and n is greater than about 70, said polyester resin being derived from the transesterification reaction of a starting DMCD and a starting CHDM wherein the trans-cis ratio of repeating units derived from DMCD is preferably greater than about 8 to 1, and the trans-cis ratio of repeating units derived from DMCD is preferable greater than about 1 to 1, said polyester resin having crystalline properties with a preferable viscosity greater than 4500 poise and a melting temperature greater than 216 degrees Centigrade.
