Abstract
1359891 Polyester film E I DU PONT DE NEMOURS & CO 6 July 1971 [7 July 1970 10 June 1971] 31625/71 Heading C3R A process for forming a thermoplastic film comprises dispersing at least 100 p.p.m. of a calcium phosphate having an average equivalent spherical particle size between 0À05 and 5 microns in a film-forming polymer prior to extrusion of the polymer to give the film. Specified calcium phosphates are tribasic calcium phosphate, anhydrous dibasic calcium phosphate and calcium pyrophosphate, and the specified polymer is biaxially oriented polyethylene terephthalate.
