Abstract
This invention relates to hot melt adhesive compositions which include a highly unsaturated hydrocarbon rubber, about 5 to about 100 parts by weight of a neutralized sulfonated elastomeric polymer per 100 parts by weight of the highly unsaturated hydrocarbon rubber, wherein the neutralized sulfonated elastomeric polymer has about 5 to about 50 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated elastomeric polymer, and about 25 to about 200 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, aliphatic dienes and mono- and di-olefins, cyclic olefins of 5 or 6 carbon atoms and hydrogenated polycyclics per 100 parts by weight of the highly unsaturated hydrocarbon rubber.
Claims14
A hot melt adhesive composition which comprises:
- (a) a highly unsaturated hydrocarbon rubber;
