Claim:
1. A method of forming a cured solid material from polymerizable resin system comprising: mixing a first Part A and a second Part B, at least one of which is a paste, that, within 6 hours after beginning mixing, obtains a working period of intermediate stage polymerization providing a manipulative state of cohesiveness characterized by a stress unit measurement of 0.5 to 2.0 kg/cm applying the mixture as an adhesive, cement, glue, sealant, a base liner, a capping agent, a material for surface or structural repair and/or filling, an encasing material, a bodily implant, a dental material, and/or as a polymeric object having a living polymer surface property before the mixture becomes a cured solid material, wherein the first Part A comprises an acid, wherein the acid comprises polyacrylic acid homopolymer or copolymer, 4-methacryloxyethyl trimellitic anhydride or 4-methacryloxyethyl trimellitic acid; wherein the second Part B comprises an organic compound that is water soluble or partially water soluble and that, in the presence of the acid can be ionized or solvated to initiate curing of one or more ethylenically unsaturated monomers or oligomers that is present in Part A, Part B, or both, wherein the organic compound is a salt of organic acid, an onium compound, protonated amines, and precursors thereof, as well as combinations thereof ; and wherein the one or more ethylenically unsaturated monomers and/or oligomers are chosen from the group consisting of acrylonitrile, acrylamide, (meth)acrylates, aldehydes, butadiene-1,3, ethylene, isoprene, methacrylic esters, methacrylamide, methyl styrene, styrene, vinyl esters, vinylidene chloride, and N-vinyl pyrrolidone, and combinations thereof.
