METHOD OF PRODUCING A THERMOPLASTIC POLYMER PREFORM AND AN ARTICLE PRODUCED THEREFROM

摘要

A method of producing a thermoplastic polymer preform having at least a crystalline finish portion comprising: (i) providing a thermoplastic polymer composition comprising a thermoplastic polymer and at least one reheat rate increasing additive; (ii) forming a preform from the thermoplastic polymer composition, wherein the preform comprises a finish portion and a body portion; and (iii) exposing at least the finish portion of the preform to energy until crystallized.
