ABSTRACT:
There is disclosed a family of new vinyl monomers capable of forming polymers by free radical polymerization. The vinyl monomer is of the formula ##STR1## wherein R.sub.1 and R.sub.2 are substituted or unsubstituted hydrocarbons, X is O, NH or NR.sub.3, and R.sub.3 is substituted or unsubstituted hydrocarbon.
The intermediates in the synthesis of these monomers are new beta-chloroanaline ureas. The polymers are useful in film and fiber formation and display good toughness. These new vinyl monomers also form a cyclic monomer.
