Melt processable resorcinol-phthalate polyesters and process for their preparation |
| abstract |
A melt processable resorcinol phthalate polyester having a terephthalic acid content not greater than about 30 mole percent is prepared by a two-stage process utilizing an alkali or alkaline earth metal acetate catalyst. The first stage yields a non-volatile pre-polymer which is then melt polymerized to the resorcinol phthalate polyester. A process for preparing a melk processable resorcinol phthalate polyester from resor- ! cinol by reacting it with an acetylating agent is also disclosed. The resulting polyester exhibits high char and low flammability in addition to being melt processable. |
