Abstract
PURPOSE: To improve the elastic modulus and hot-water resistance of a crystalline polyester, without lowering the crystallinity, by adding a specific aromatic ester.
CONSTITUTION: 100 parts by weight of a linear crystalline polyester (e.g. polyethylene terephthalate) is compounded with 0.1W20 parts of an aromatic ester of formula I or II (R is alkyl, alkoxy, ester, etc.) having a characteristics of a liquid crystal with a nematic melting point of ≥120°C. For example, the liquid crystal compound is mixed with the polyester by an extruder, a kneader, etc., or is attached to the pellets of the polyester.
EFFECT: Useful for manufacturing of film, tape, bottles, and food containers.
