Claims
- 1. A polymer having cyclic urea pendant groups represented by the formula (IV): ##STR18## wherein X is an oxygen atom, a sulfur atom or --NR.sub.6 -- wherein R.sub.6 is a hydrogen atom or a C.sub.1 -C.sub.5 alkyl group and n is 0 or an integer of 1 to 4.
- 2. A polymer of claim 1, in which the pendant group is contained in the amount of 0.1-88 percent by weight based on the total weight of the polymer, and the molecular weight of the polymer excepting the pendant group is about 500-100,000.
- 3. A polymer of claim 2, in which the content of the pendant group is about 5-90%.
- 4. A self-curable polymer of claim 1, in which the polymer is a homopolymer of a monomer having a cyclic urea pendant group represented by the formula (IV) or a copolymer of two or more monomers having said pendant cyclic urea groups.
- 5. A self-curable polymer of claim 1, in which the polymer is a copolymer of one or more monomers having a cyclic urea pendant group represented by the formula (IV) and other one or more monomers having a polymerizable unsaturated bond but no pendant group represented by the formula (IV).
- 6. A self-curable polymer of claim 5, in which the monomer to be polymerized with the monomer having the pendant group is selected from the group consisting of mono or diolefins, esters having a polymerizable unsaturated double bond, nitriles having a polymerizable unsaturated double bond, amides having a polymerizable unsaturated double bond, alcohols having a polymerizable unsaturated double bond, acids of .alpha.,.beta.-ethylenically unsaturated bond, and unsaturated sulfonic acid.
- 7. The polymer of claim 1, wherein X is an oxygen atom.
