摘要： Disclosed herein are a novel graft copolymer comprising a stock copolymer (A) of at least one monomer selected from esters of unsaturated carboxylic acids and vinyl esters (a), ethylene (b) and carbon monoxide (c), and a polyamide oligomer having a primary amino group at one end of its molecule (B) grafted on said stock copolymer, and a process for the preparation thereof. The proposed graft copolymer, when used as an adhesive, in particular for adhesion of polyvinyl chloride, exhibits excellent heat resistance and adhesion properties.

摘要： Glass bottles, suitable as containers for drinks, such as beer and fruit juice, are coated with a single layer of a thermally cured material formed of a powdery composition comprising a mixture of (i) a blocked organic polyisocyanate and (ii) a hydrolyzed ethylene-vinyl ester copolymer and/or a carboxyl-modified version of said hydrolyzed copolymer. The coated bottles are highly effective in the prevention of scattering of glass fragments in the event of breakage and excellent in clarity, alkali resistance, abrasion resistance, scratch resistance and weathering quality.
