Abstract

1,214,387. Making polyester flakes. GOODYEAR TIRE & RUBBER CO. 21 Oct., 1968 [6 Nov., 1967], No. 49826/68. Heading C3R. An aromatic polyester is made into thin flakes by subjecting substantially amorphous particles of the polyester to a compressive force, whereby they are flattened into flakes and simultaneously attain a degree of crystallization of at least 10%. The examples describe the rolling of cubes of polyethylene terephthalate between steel rollers under varying roll clearances and at temperatures from room temperature to 200‹ C.
