摘要： An adhesive composition containing a polyvinyl alcohol-stabilized butadiene polymer latex and a methylene donor compound. The butadiene polymer latex is prepared by an emulsion polymerization in the presence of polyvinyl alcohol. The adhesive composition may also contain other optional ingredients such as a supplemental polymeric film-forming component, a nitroso compound crosslinker, a maleimide compound crosslinker, a vulcanizing agent, and an acid-scavenging compound. The polyvinyl alcohol-stabilized butadiene polymer latex and methylene donor compound combine to provide a tightly crosslinked, robust film which provides for excellent adhesion and environmental resistance.
