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.sub.1 and R.sub.2 are selected from the group consisting of acryloyloxy and lower alkyl acryloyloxy; R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 are selected from the group consisting of hydrogen and lower alkyl; R.sub.9 and R.sub.10 are selected from the group consisting of hydrogen, lower alkyl, lower hydroxyalkyl, lower hydroxyalkyl acryloyloxy, and lower hydroxyalkyl methacryloyloxy; and R.sub.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.
