Claims
- 1. An acetylenic monomer of the formula [R(C.tbd.C).sub.a (CH.sub.2).sub.b (C.tbd.C).sub.b-1 ].sub.2 wherein a is 1 or 2; and b is 0 when a is 1; b is 0, 1, or 2 when a is 2; and (b-1) is taken as zero whenever b is zero; and wherein R is --(CH.sub.2).sub.n O(C.dbd.O)NHCH.sub.2 CO.sub.2 M, with n being an integer of from 1 to 10 and M being H or alkali metal.
