METHOD OF REDUCING ACETALDEHYDE IN POLYESTERS, AND POLYESTERS THEREFROM
摘要
Acetaldehyde production in a polyester may be reduced by using a formulation which comprises an acetaldehyde scavenger and a phosphorous additive. The two materials appear to act synergistically in reducing acetaldehyde production. Preferred formulations comprise anthranilamide and phosphorous acid and are used in combination with aluminium or titanium catalysed PET resins.
