Abstract
Compositions comprising at least one adduct of perhalogenated cyclic conjugated dienes and olefinically-unsaturated dienophiles having a vinyl content in excess of 50 percent have been found to be unexpectedly effective adhesive systems for bonding a variety of elastomeric materials, including vulcanizable and vulcanized natural and synthetic elastomer compositions, to themselves and other structural substrates.
Claims2
An adhesive composition suitable for bonding elastomeric materials consisting essentially of
- (a) at least one Diels-Alder adduct of a chlorinated cyclic conjugated diene and 1,2 polybutadiene homopolymer having a vinyl content in the range from 88 to 98 percent, based on total unsaturation, and a molecular weight in the range from 500 to 200,000, and said Diels-Alder adduct has a halogen content in the range from 26 to 35 weight percent, based on total weight of said Diels-Alkder adduct;
- and
- (b) An inert solvent, said solvent being present in an amount to provide a lacquer composition suitable for use as an adhesive suitable for bonding elastomeric materials, said lacquer having a total solids content in the range from 5 to 40 percent.
