Abstract
Abstract This invention relates to hot melt adhesive compositions which include an elastomeric co- or terpolymer, about 5 to about 100 parts by weight of a neutralized sulfonated co- or terpolymer per 100 parts by weight of the highly unsaturated hydrocarbon rubber, wherein the neutralized sulfonated elastomeric polymer has about 0.2 to about 5 weight percent of chemically combined sulfur 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 diolefins, cyclic olefins of 5 to 6 carbon atoms and hydrogenated poly cyclics per 100 parts by weight of the neutralized sulfonated co- or terpolymer rubber.

Claim 1
Independent Claim
163 words
An adhesive composition which comprises: (a) a neutralized sulfonate containing polymer having about 0.2 to 3 weight percent of chemically combined sulfur wherein said neutralized sulfonated co- or terpolymer comprises at least 80% by weight of at least one conjugated diene having from 4 to 12 carbon atoms and a minor proportion of a metal or amine neutralized sulfonate monomer characterized by the formula: ##STR6## where X is (CH 2 ) n , or aromatic, wherein n=0, 1, 2, 3, 4, and Y is a cation selected from Groups IA, IIA, IB and IIB of the periodic table or an amine of the formula: ##STR7## where R 1 and R 2 can be aliphatic groups of C 1 to C 12 or hydrogen, said co- or terpolymer being water insoluble; and (b) about 25 to about 200 parts by weight of a hydrocarbon tackifying resin based on a petroleum or coal tar distillate per 100 parts by weight of said sulfonate containing polymer.
