Abstract: Fiber coatings with low Young's modulus and high tear strength are realized with coating compositions that include an oligomeric material formed from an isocyanate, a hydroxy acrylate compound and a polyol. The oligomeric material includes a polyether urethane acrylate and a di-adduct compound, where the di-adduct compound is present in an amount of at least 2.35 wt %. The reaction mixture used to form the oligomeric material may include a molar ratio of isocyanate:hydroxy acrylate:polyol of n:m:p, where n may be greater than 3.0, m may be between n?1 and 2n?4, and p may be 2. Young's modulus and tear strength of coatings made from the compositions increase with increasing n. Coatings formed from the present oligomers feature high tear strength for a given Young's modulus.

Abstract: The present invention provides a method of making a methylene malonate monomer that includes the steps of reacting a malonic acid ester with a source of formaldehyde optionally in the presence of an acidic or basic catalyst and optionally in the presence of an acidic or non-acidic solvent to form reaction complex.

Abstract: The present invention provides improved methods for the chemical synthesis of methylene malonates using the Knovenagel synthesis reaction. The method of the invention provides for improved methylene malonates by significantly reducing or eliminating the formation of alternative and/or deleterious side products, significantly reducing or eliminating unwanted consumption of methylene malonates, and significantly reducing or eliminating the degradation of methylene malonates. These advantages result in methylene malonates, which upon recovery, are of higher quality, greater purity, improved yield and possess overall improved performance characteristics (e.g., improved cure speed, retention of cure speed, improved shelf-life and/or stability).
