Easily alkali soluble polyester and method for producing the same |
| abstract |
A spinnable, gel-free and thermally stable polyester composition includes at least one dicarboxylic acid or monoesters thereof or diesters thereof; at least one diol; at least one carboxylic acid anhydride; at least one sodium or lithium based aromatic co-monomer and at least one hydroxyl terminated polyester polyol. The polyester is produced by esterifying at least one dicarboxylic acid or monoesters thereof or diesters thereof and at least one diol along with at least one acid anhydride at a temperature in the range of 250° C. to 290° C. and pressure in the range of 0 kg/cm 2 g to 5 kg/cm 2 g; and polycondensing the esterified mixture along with at least one sodium or lithium based aromatic compound and at least one hydroxyl terminated polyether polyol at a temperature in the range of 250° C. to 290° C. and under vacuum of 0.1 torr to 10 torr. |
