Abstract: This invention is directed to fast curing polymer compositions, These compositions comprise a blend of (1) a polymer having pendent activated acetylenic groups and ammonia or a comonomer having at least two functional groups which are reactive with the activated acetylenic groups of the polymer, or (2) a blend of a monomer having at least two activated acetylenic groups and ammonia and/or a comonomer having at least two functional groups which are reactive with the activated acetylenic groups of the monomer.
