Abstract
Abstract This invention relates to emulsion type adhesive compositions which include a metal neutralized sulfonated elastomeric co- or terpolymer, wherein the neutralized sulfonated copolymer has about 5 to about 250 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated copolymer, and less than about 200 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, having about 5 to 6 carbon atoms, the hydrocarbon resin being composed of aliphatic dienes and monoolefins per 100 parts by weight of the neutralized sulfonated co- or terpolymer.

Claim 2
Dependent Claim
93 words
An adhesive composition derived from a composition which consists of a mixture of: (a) an emulsion of a metal neutralized sulfonated elastomeric co or terpolymer, said neutralized sulfonated co- or terpolymer having about 5 to about 250 meq. of neutralized sulfonated groups per 100 grams of said metal neutralized sulfonated co- or terpolymer; and (b) about 25 to about 200 parts by weight of an emulsion of a hydrocarbon tackifying resin based on a petroleum or coal tar distillate per 100 parts by weight of said metal neutralized sulfonated elastomeric co- or terpolymer.
Claim 3
Dependent Claim
198 words
An adhesive composition according to claim 1, wherein said emulsion of metal neutralized sulfonated elastomeric co- or terpolymer comprises at least 80% by weight of at least one conjugated diene having from 4 to 12 carbon atoms or a combination of at least 80% by weight of at least one conjugated diene and styrene, wherein the combination contains less than 50 weight percent styrene of the total 80 weight percent 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, substantially gel-free, thermally stable and oxidatively stable having at least 0.5 weight percent chemically combined to less than 5 weight percent chemical combined sulfur, with a reduced viscosity as measured in a solvent at a concentration of 10 gm/liter of greater than 0.2 and less than 5.0.
