A copolymer of an α-olefin with an aromatic diolefin such as divinylbenzene produced by means of Ziegler-Natta polymerization and having a vinylphenyl moiety is subjected to polymerization with an ethylenically unsaturated monomer by means of anion polymerization or free radical polymerization, whereby a graft-modified α-olefin copolymer is obtained.
A laminate suitable for use as wrapping or packaging materials for foods and industrial materials is disclosed, which is produced by laminating a thermoplastic resin composition which comprises (1) 10 to 95 % by weight of an ethylene copolymer composed mainly of units derived from ethylene and units derived from an unsaturated carboxylic acid anhydride and (2) 70 to 5 % by weight of a flexible resin having an MFR (190°C) of 0.1 to 1,000 g/10 min, to one or more kinds of substrates selected from thermoplastic resins, metals, papers, and fabrics. A process for efficiently producing the laminate is also disclosed.
Disclosed is an aqueous coating composition which keeps in high nonvolatile contents during coating operation and capable of being effectively applied even under a relatively high humidity condition. The coating composition imparts high orientation of metallic pigment particles to the cured film. The aqueous coating composition of the present invention comprises a specific acryl polymer varnish (a) and a specific urethane oligomer dispersion.
