Abstract
Polymers comprising randomly repeating units of the general formula ##STR1## wherein R.sub.1 is linear or branched C.sub.1 -C.sub.10 alkoxy, R.sub.2 is linear or branched C.sub.1 -C.sub.10 alkyl, hydrogen or halogen, and W is C.sub.2 to C.sub.10 alkenyl-substituted aryloxy. These novel polymers are elastomers and may be used to form flexible and semirigid foams and coatings. They display good fire retardance and low smoke levels.
