Abstract
Abstract Polymers are prepared by reacting a particular class of monomer with a curing agent selected from the group consisting of hydrogen peroxide, organic peroxides, and organic hydroperoxides. The monomers are characterized by the general formula: ##EQU1## wherein x is an integer from 0 to 3; y is an integer from O to x; and R 1 and R 2 are selected from the group consisting of acryloyloxy and lower alkyl acryloyloxy; R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 are selected from the group consisting of hydrogen and lower alkyl; R 9 and R 10 are selected from the group consisting of hydrogen, lower alkyl, lower hydroxyalkyl, lower hydroxyalkyl acryloyloxy, and lower hydroxyalkyl methacryloyloxy; and R 11 is a lower alkylene group linking two nitrogen atoms. The invention also provides a two-component sealant system which includes a second component comprising a curing agent dissolved in a volatile solvent.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A two-component sealant system which is shelf-stable before said components are combined, and which is capable of setting up on combination of said components, comprising: separate first and second components which, when mixed, form a polymer, said first component comprising an amine salt of a monomer characterized by the formula: ##EQU2## wherein R 1 and R 2 are selected from the group consisting of hydrogen and lower alkyl and R 3 is selected from the group consisting of lower alkyl and lower hydroxyalkyl, said amine salt being prepared by reacting said monomer with an acid selected from the group consisting of acrylic acid and lower alkyl acrylic acids; and said second component comprising a curing agent, said curing agent being selected from the group consisting of hydrogen peroxide, organic peroxides and organic hydroperoxides.
Claim 2
Dependent Claim
133 words
A two-component sealant system which is shelf-stable before said components are combined, and which is capable of setting up on combination of said components, comprising: separate first and second components which, when mixed, form a polymer, said first component comprising an amine salt of a monomer characterized by the formula: ##EQU2## wherein R 1 and R 2 are selected from the group consisting of hydrogen and lower alkyl and R 3 is selected from the group consisting of lower alkyl and lower hydroxyalkyl, said amine salt being prepared by reacting said monomer with an acid selected from the group consisting of acrylic acid and lower alkyl acrylic acids; and said second component comprising a curing agent, said curing agent being selected from the group consisting of hydrogen peroxide, organic peroxides and organic hydroperoxides.
