Copolymer consists of 50-97 wt.% ethylene and 3-50 wt.% of the glycidyl ester of acrylic, methacrylic or ethacrylic acid. The copolymer may be used alone or modified with a filler, synthetic resin and plasticiser as a moulding comp. for the manufacture of films and coatings. At above 200 deg.C., the copolymer is cross-linkable and is also highly useful as an adhesive e.g. in the lamination of metals, wood, paper and glass. The copolymer is produced at 100-300 deg.C. at a pressure above 500 atmos. e.g. at 10,000-50,000 psi., in the presence of a free radical generator, e.g. azobisisobutyronitrile EtOOEt, H2O2 and alkali metal persulphates, percarbonates. The pref. glycidyl ester is the methacrylate. |
