Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A pressure-sensitive adhesive comprising: (1) a rubbery polymer having an alkadienol constituent and (2) an adhesion promoter conforming to the formula (R"Z)nY wherein Y is Si, B or CO; wherein Z is O, S, NH or NR" with the proviso that Z can be NH or NR" only when Y is Si; wherein n is 2 if Y is CO, 3 if Y is B and 4 if Y is Si; and wherein the R" groups are the same or different and are chosen from alkyl or cycloalkyl groups containing from 1 to about 18 carbon atoms per group.
Claim 2
Dependent Claim
99 words
A pressure-sensitive adhesive comprising: (1) a rubbery polymer having an alkadienol constituent and (2) an adhesion promoter conforming to the formula (R"Z)nY wherein Y is Si, B or CO; wherein Z is O, S, NH or NR" with the proviso that Z can be NH or NR" only when Y is Si; wherein n is 2 if Y is CO, 3 if Y is B and 4 if Y is Si; and wherein the R" groups are the same or different and are chosen from alkyl or cycloalkyl groups containing from 1 to about 18 carbon atoms per group.
Claim 3
Dependent Claim
18 words
An adhesive of claim 1 wherein said rubbery polymer is prepared from at least one monohydroxyalkyl-substituted conjugated diene.
Claim 4
Dependent Claim
67 words
An adhesive of claim 2 wherein said rubbery polymer is prepared from monomers conforming to the formula ##STR4## wherein R represents hydrogen, alkyl, cycloalkyl, aryl, aralkyl, alkaryl, or alkylcycloalkyl, with the R groups the same or different and wherein Q represents R as defined above or a hydroxyalkyl group represented by ##STR5## wherein each R' is hydrogen, methyl, or ethyl and n is 1, 2 or 3.
Claim 5
Dependent Claim
60 words
A pressure-sensitive adhesive comprising: (1) a rubbery polymer having an alkadienol constituent and (2) an adhesion promoter conforming to the formula ##STR6## wherein R'" is methyl, ethyl or n-propyl; wherein R" is alkyl or cycloalkyl containing from about 1 to about 18 carbon atoms per group and wherein m is 0 or an integer of from 1 to about 30.
Claim 6
Dependent Claim
60 words
