Abstract

1,272,584. Deodorizing polymers of unsaturated esters. FISONS INDUSTRIAL CHEMICALS Ltd. 2 Oct., 1969 [5 July, 1968], No. 32330/68. Heading C3P. The odours associafed with a polymer or blend of polymers obtained wholly or in part by the homo- or co-polymerization of a carboxylic acid ester monomer, in which the alcohol and/or acid moiety contains ethylenic unsaturation, are reduced by treating the polymer or polymer blend with a hydrazine compound of the formula R<SP>1</SP>R<SP>2</SP>NNHR<SP>3</SP> or a hydrate thereof, R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> being the same or different and representing H or alkyl, the amount of the hydrazine compound used being the equivalent of from 0À1-5% by weight of hydrazine based on the weight of polymer or polymer blend treated. The polymers may be derived from alkyl maleate, acrylate or methacrylate esters and vinyl esters such as vinyl acetate. They may be homopolymers or copolymers of two or more such esters or copolymers with other monomers such as acrylonitrile, butadrene or styrene. Examples of polymer blends are polymethyl acrylate with polybutyl acrylate; and ethylene-vinyl acetate copolymer with polyethylene. The polymer or blend is suitably treated in the form of an aqueous emulsion, dispersion or suspension.
