Abstract

250,949. British Thomson-Houston Co., Ltd., (Assignees of Peterson, C. F.). April 14, 1925, [Convention date]. Ester polymerization products.-The curing of artificial resins of the type formed by the reaction of a polyhydric alcohol with a polybasic acid, such as those described in Specification 3271/13 and 8417/13, [Class 70, India rubber &c.], is accelerated by the addition of a phenol resin. A small quantity of bakelite added to glyptal (a compound of glycerine and phthalic acid) will produce the same degree of polymerization in two minutes at 150‹-250‹ as is produced by heating glyptal alone for 25-30 min.
