Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
50 words
A method of adhesively bonding comprising (a) mixing a polyisocyanate with a polyol comprised of a hydroxymethyl fatty polyol or an alkylene oxide derivative thereof, (b) applying the mixture to a substrate and (c) contacting the applied mixture with a surface of an article to be bonded to the substrate.
Claim 2
Independent Claim
50 words
A method of adhesively bonding comprising (a) mixing a polyisocyanate with a polyol comprised of a hydroxymethyl fatty polyol or an alkylene oxide derivative thereof, (b) applying the mixture to a substrate and (c) contacting the applied mixture with a surface of an article to be bonded to the substrate.
Claim 3
Dependent Claim
20 words
A method in accordance with claim 1 wherein the mixture is comprised of a hydroxymethyl fatty polyol which is 9,9(10,10)-bis(hydroxymethyl)octadecanol.
Claim 4
Dependent Claim
20 words
A method in accordance with claim 1 wherein the mixture is comprised of a hydroxymethyl fatty polyol which is 9(10)-(hydroxymethyl)octadecanol.
Claim 5
Dependent Claim
30 words
A method in accordance with claim 1 wherein the polyol is further comprised of an amount of a long-chain polyether copolyol sufficient to lessen the rigidity of the resulting adhesive.
Claim 6
Dependent Claim
26 words
A method in accordance with claim 4 wherein the long-chain polyether copolyol is a polyoxytetramethylene diol having a molecular weight in excess of about 400 g/mol.
Claim 7
Dependent Claim
16 words
A method in accordance with claim 4 wherein the long-chain polyether copolyol is a propoxylated trimethylolpropane.
Claim 8
Dependent Claim
10 words
A bonded article prepared by the method of claim 1.
Claim 9
Dependent Claim
34 words
A bonded article in accordance with claim 7 wherein the adhesive composition is prepared from a mixture further comprising an amount of a long-chain polyether sufficient to lessen the rigidity of the resulting adhesive.
