| 20110082314 | METHOD FOR PRODUCING POLYALKYLENE GLYCOLDI(METH)ACRYLATES - The present invention relates to a process for preparing polyalkylene glycol di(meth)acrylates by reacting polyalkylene glycol with (meth)acrylic anhydride, wherein the reaction mixture contains at most 0.5% by weight of metal compounds and/or amines, the reaction is carried out in the presence of polymerization inhibitors and the reaction temperature is at least 60° C. | 04-07-2011 |
| 20140357889 | SYNTHESIS OF POLYFUNCTIONAL POLYOL ACRYLATES - A method of synthesizing urethane-free polyfunctional acrylate compounds. The method includes reaction of a polyol with acrylic acid in the presence of an inhibitor. A catalyst may also be present. The catalyst may be an acid and the inhibitor may be a substituted phenol compound. Excess acid may be removed by adding a salt and excess water may be removed by adding a drying agent. The reaction converts alcohol groups of the polyol to acrylate groups to provide a radiation-curable polyfunctional acrylate compound. The reaction is applicable to polyols generally and provides a scalable high yield process for forming urethane-free polyfunctional acrylates over a wide range of molecular weights. Coatings made from the acrylate products exhibit modulus and tensile strength characteristics favorable for primary fiber coatings. | 12-04-2014 |
