| titleOfInvention | An improved process for the production of slow crystallizing polyester resin |
| abstract | Continuous process for slow crystallizing polyester resin comprising esterification of at least one dicarboxylic acid or mono-esters thereof or di-esters thereof with at least one polyol, melt polymerizing the esterified mixture, preparing uniform crystalline hemispherical prepolymer by particle former process, adding at least one diol having tertiary or quaternary carbon atoms with pendant groups such as neopentyl glycol or 2-methyl-1,3propanediol or any suitable diol at any stage during esterification or melt polymerization but before the particle former process; and solid state polymerizing the prepolymer to obtain high molecular weight slow crystallizing polyester. Using the slow crystallizing polyester resin process to prepare low molecular weight crystalline hemispherical prepolymer of uniform hemispherical shape, uniform particle size, and uniform crystallinity as a precursor to high molecular weight resin or to prepare high molecular weight polyester resin for thick walled transparent preforms, large containers, films or sheets with accepted clarity. |
