摘要:A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.

标题 :Synthesis of oligomer for optical fiber coating
发明人：CHEN YANGBIN; YANG BIN
权利人:CORNING INC
摘要:A method for making oligomers is described. The method includes reacting a polyol with a precursor having mixed functionality. The precursor includes a curable functional group and an isocyanate group capable of reacting with an alcohol group of the polyol. The precursor reacts with the alcohol group of the polyol to form a urethane linkage and to add a covalently bonded curable functional group to the polyol. The oligomers can be included in coating compositions for optical fiber and lead to coatings having improved tear strength.
