THERMOPLASTIC CONTACT ADHESIVES, PREPARATION AND USE THEREOF

23189-5856 The present invention relates to a new thermoplastic contact adhesive, containing: (a) from 60 to 100 parts, by weight, of a graft copolymer composed of from 65 to 97%, by weight of graft base consisting of a copolymer of from 45 to 65% by weight, of ethylene units with from 35 to 55% by weight, of vinyl acetate units and optionally up to 10%, by weight of units of other unsaturated compounds, and from 35 to 3% by weight of grafted monomer units, consisting of from 80 to 100% by weight, of methyl, methacrylate units and from 0 to 20% by weight, of units of other unsaturated compounds; (b) from 3 to 50 parts, by weight, of a plasticizer containing epoxide groups or of a mixture of various plasticizers containing epoxide groups; (c) from 60 to 200 parts, by weight, of an adhesifying resin; and (d) from 0 to 20 parts, by weight, of other additives; characterised in that the plasticizers containing epoxide groups are epoxidized oils or epoxidized fatty acid esters of alcohols having from 1 to 12 carbon atoms. The new adhesives have high heat resistance and bond strength. Le A 22 694
