Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
33 words
The adhesive composition of claim 1 wherein the ether plasticizer has the formula R1OR2 wherein R1 is an aryl group and R2 is an organic radical containing up to about 20 carbon atoms.
Claim 2
Dependent Claim
21 words
The adhesive composition of claim 2 wherein R1 contains up to about 20 carbon atoms and R2 is a hydrocarbon group.
Claim 3
Dependent Claim
23 words
The adhesive composition of claim 3 wherein each of R1 and R2 is an aryl group containing up to about 20 carbon atoms.
Claim 4
Dependent Claim
37 words
The adhesive composition of claim 4 wherein each of R1 and R2 is a phenyl radical, each containing up to 5 substitutents selected from the class consisting of chlorine, bromine and C1 to about C20 alkyl radicals.
Claim 5
Dependent Claim
24 words
The adhesive composition of claim 5 wherein the ether plasticizer comprises from about 0.5 percent to about 10 percent by weight of the composition.
Claim 6
Dependent Claim
30 words
The adhesive composition of claim 1 wherein the ester of Alpha -cyanoacrylic acid has the formula wherein R is a C1 to about C16 alkyl, alkenyl, cyclohexyl or phenyl group.
Claim 7
Dependent Claim
21 words
The adhesive composition of claim 7 wherein the ester of Alpha -cyanoacrylic acid is methyl- Alpha -cyanoacrylate or ethyl- Alpha -cyanoacrylate.
Claim 8
Dependent Claim
14 words
The adhesive composition of claim 1 which additionally contains an inhibitor of anionic polymerization.
Claim 9
Dependent Claim
15 words
The adhesive composition of claim 9 which additionally contains an inhibitor of free radical polymerization.
Claim 10
Independent Claim
48 words
The method of improving a cyanoacrylate ester adhesive composition which comprises adding thereto from about 0.25 percent to about 15 percent by weight of the composition of an aryl or diaryl ether plasticizer, wherein the aromatic ring of each aryl group is directly bonded to the ethereal oxygen.
Claim 11
Dependent Claim
75 words
In the process of bonding substrates with a cyanoacrylate ester adhesive composition, the improvement wherein the adhesive composition comprises a cyanoacrylate ester of the formula wherein R is a C1 to about C16 alkyl, alkenyl, cyclohexyl or phenyl group; and from about 0.25 percent to about 15 percent by weight of said composition of an aryl or diaryl ether plasticizer wherein the aromatic ring of each aryl group is directly bonded to the ethereal oxygen.
Claim 12
Dependent Claim
45 words
The method of claim 11 wherein the adhesive composition comprises an ester of Alpha -cyanoacrylic acid having the formula wherein R is a C1 to about C16 alkyl, alkenyl, cyclohexyl or phenyl group, an inhibitor of anionic polymerization and an inhibitor of free radical polymerization.
