Adhesives coatings and laminates utilizing ethylene copolymers and coal-tar pitch |
摘要 |
Thermoplastic compositions of matter comprising coal-tar pitch and a material selected from (1) a terpolymer of ethylene, vinyl acetate, and an ethylenically-unsaturated carboxylic acid and (2) a mixture of copolymers of ethylene and vinyl acetate and of ethylene and an ethylenically-unsaturated carboxylic acid, exhibiting high strength in shear and peel over a wide temperature range, are prepared and used as adhesives and coatings. Laminated materials utilizing such compositions of matter are also disclosed.
