Process for crystallizing at least a portion of a crystallizable condensation homopolymer to form solid particles |
摘要 |
A process for forming solid particles comprising the steps of: combining in molten form a major component of a crystallizable condensation homopolymer and a minor component of a non-crystallizable condensation polymer, wherein the crystallizable condensation homopolymer and the non-crystallizable condensation polymer each have a degree of polymerization of 10 to less than 48 prior to the combining; mixing the combined crystallizable condensation homopolymer and non-crystallizable condensation polymer in molten form to form a mixture that comprises 10 to 30 mol % of the non-crystallizable condensation polymer; forming the mixture into droplets; exposing the droplets to a thermal environment which results in the bulk of the droplet reaching within 15 seconds a temperature within ±10° C. of the temperature at which the maximum rate of crystallization of the crystallizable condensation homopolymer occurs; and crystallizing at least a portion of the crystallizable condensation homopolymer in the mixture to form solid particles.
