Process for preparation of polyesters with improved molecular weight from glycols containing a vicinal secondary hydroxyl group |
| abstract |
Disclosed is a process for the preparation of polyesters from aromatic dicarboxylic acids or derivatives thereof and diols containing vicinal hydroxyl groups at least one of which is secondary. The use of a tin catalyst results in the formation of polyesters having I.V.'s of at least about 0.4 when the diol has two secondary hydroxyl groups and at least about 0.7 when the diol has only one secondary hydroxyl group. |
