Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
65 words
An adhesive composition comprising: a. 5 to 50% by weight of a graft copolymer of a block copolymer and a polymerized alkyl ester of an acid of the acrylic acid series wherein said block copolymer is selected from the group consisting of monoalkenyl arene-conjugated diene block copolymers and selectively hydrogenated monoalkenylarene-conjugated diene block copolymers; and b. 95% to 50% by weight of a polyurethane cement.
Claim 2
Dependent Claim
65 words
An adhesive composition comprising: a. 5 to 50% by weight of a graft copolymer of a block copolymer and a polymerized alkyl ester of an acid of the acrylic acid series wherein said block copolymer is selected from the group consisting of monoalkenyl arene-conjugated diene block copolymers and selectively hydrogenated monoalkenylarene-conjugated diene block copolymers; and b. 95% to 50% by weight of a polyurethane cement.
Claim 3
Dependent Claim
72 words
A laminate comprising: a. a first substrate comprising a block copolymer having at least one polymer block of the group consisting of polymer blocks of conjugated dienes and hydrogenated polymer blocks of conjugated dienes, and at least two polymer blocks of a monoalkenylarene; b. a second substrate of the group consisting of a textile, polyvinyl chloride, leather, metal and glass; c. and as a bond therebetween a composition according to claim 1.
