Abstract
Abstract This invention relates to hot melt adhesive compositions which include a neutralized sulfonated 1,2-syndiotactic polybutadiene resin which has about 5 to about 25 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated 1,2-syndiotactic polybutadiene, and about 25 to about 250 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, having about 5 to about 6 carbon atoms the hydrocarbon resin being composed of aliphatic dienes and monoolefins per 100 parts by weight of the neutralized sulfonated 1,2-syndiotactic polybutadiene polymer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A hot melt adhesive composition which consists essentially of: (a) a neutralized sulfonated 1,2-syndiotactic polybutadiene resin, said neutralized sulfonated 1,2-syndiotactic polybutadiene resin having about 5 to about 50 meq. of neutralized sulfonate groups per 100 grams of said neutralized sulfonated 1,2-syndiotactic polybutadiene resin, wherein said neutralized sulfonate groups of said sulfonated 1,2-syndiotactic polybutadiene polymer are neutralized with a counterion selected from the group consisting of ammonium, aluminum, antimony, iron, lead and Groups IA, IIA, IB and IIB of the Periodic Table of Elements; and (b) about 25 to about 250 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate per 100 parts by weight of said neutralized sulfonated 1,2-syndiotactic polybutadiene polymer.
Claim 2
Dependent Claim
116 words
A hot melt adhesive composition which consists essentially of: (a) a neutralized sulfonated 1,2-syndiotactic polybutadiene resin, said neutralized sulfonated 1,2-syndiotactic polybutadiene resin having about 5 to about 50 meq. of neutralized sulfonate groups per 100 grams of said neutralized sulfonated 1,2-syndiotactic polybutadiene resin, wherein said neutralized sulfonate groups of said sulfonated 1,2-syndiotactic polybutadiene polymer are neutralized with a counterion selected from the group consisting of ammonium, aluminum, antimony, iron, lead and Groups IA, IIA, IB and IIB of the Periodic Table of Elements; and (b) about 25 to about 250 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate per 100 parts by weight of said neutralized sulfonated 1,2-syndiotactic polybutadiene polymer.
Claim 3
Dependent Claim
25 words
A hot melt adhesive composition according to claim 1, wherein said neutralized sulfonate groups of said sulfonated 1,2-syndiotactic polybutadiene polymer are neutralized with zinc ions.
Claim 4
Dependent Claim
82 words
A hot melt adhesive according to claim 1 further including about 1 to about 50 parts by weight of an ionic preferential plasticizer per 100 parts by weight of said neutralized sulfonated 1,2-syndiotactic polybutadiene polymer, wherein said preferential plasticizer is selected from the group consisting of carboxylic acids having about 8 to about 22 carbon atoms, metallic salts of said carboxylic acids, amides having an aliphatic group of about 8 to about 22 carbon atoms, amines, ureas and thioureas and mixtures thereof.
Claim 5
Dependent Claim
32 words
