    摘要: The use of certain imidazole derivatives such as 1-benzyl-2-methyl-imidazole, 1-benzyl-imidazole, 1-hydroxyethyl-2-phenyl-4,5-dihydroimidazole, 2-phenyl-4,5-dihydroimidazole and N,N'-carbonyldiimidazole as primer in the bonding of molded parts, especially parts made of polyolefins, with cyanoacrylate adhesives gives bonds with high strengths, even when the application of adhesive is delayed for rather long"open" times after the application of the primer.
