| titleOfInvention | Copolyester |
| abstract | It has been determined that the glass transition temperature of polyesters can be increased by incorporating certain imide-containing diacid monomers therein. This invention specifically discloses a copolyester which is comprised of repeat units which are derived from (a) a diol component and (b) a diacid component which is comprised of (1) from about 1 to about 15 mole percent of at least one imide-containing diacid monomer having the structural formula:n n wherein R represents an alkylene group, a substituted alkylene group, an arylene group, or a substituted arylene group, and (2) from about 85 to about 99 mole percent terephthalic acid or a diester thereof. N,N'-bis(1,3-methylene)cyclohexane bis-(trimellitimide) is a highly preferred imide-containing diacid monomer which can be utilized in making the polyesters of this invention. |
