A method of decreasing aldehyde content in polymeric materials, for example in bottles comprising polyethylene terephthalate, uses a compound (A) which comprises first, second and third fragments which comprise a moiety Formula A) (A) and a moiety. (Formula B) NH (B). 

Method of decreasing aldehyde content in a polymeric material

A method of decreasing aldehyde content in a polymeric material such as polyethylene terephthalate which includes contacting the polymeric material with a compound including first, second and third fragments each having a moiety and a moiety NH.

The present invention relates to the use of a fatty acid ester as a slip additive in the production of molded polyethylene terephthalate articles, to a thermoplastic molding composition comprising a polyethylene terephthalate and a fatty acid ester selected to be effective for reducing the co-efficient of friction of molded articles formed from the composition, to a molded polyethylene terephthalate article comprising a fatty acid ester selected to be effective in reducing the co-efficient of friction of the molded article, and to a process for producing a molded thermoplastic article comprising providing a thermoplastic molding composition comprising polyethylene terephthalate, admixing with the thermoplastic molding composition at least one fatty acid ester selected to be effective in reducing the co-efficient of friction of the molded article, heating the composition and molding the hot composition so as to form a molded article.
