Abstract

863,573. Polymerizing dicarboxylic acid esters. FOOD MACHINERY & CHEMICAL CORPORATION. April 1, 1957 [April 2, 1956], No. 9202/57. Class 2(6). A fusible polymer, capable of further polymerization, is made by polymerizing a diallyl or dimethallyl ester of a dicarboxylic acid in the presence of hydrogen peroxide and an organic diluent. The diluent, which may be methanol, ethanol, isopropanol, benzene, toluene, xylene, ethylbenzene or isopropylbenzene, may be used in amount of 5 to 50% by weight of the ester and diluent. Water in amount up to 1% by weight can be tolerated in the reaction mixture, and an organic peroxide may also be added to the reaction mixture preferably in amount not greater than the amount of the H 2 O 2 . Polymerization proceeds at 85‹ to 200‹C. under atmospheric pressure, though other pressures may be used. The H 2 O 2 , generally as a 30% aqueous solution, is used in amount of 0À08 to 5À0% by weight of the monomer. In Examples (1, 3 to 7) diallyl phthalate, isopropanol and aqueous H 2 O 2 were charged into a reactor, agitated and heated to'reflux (104‹-108‹C.) for about 10 hours; the batch was then cooled, mixed with isopropanol and the polymer which precipitated at 0‹C. was separated by filtration; (2) dimethallylphthalate was similarly polymerized. Other esters specified are diallyl-isophthalate, -maleate, -itaconate, -adipate and -dithioglycollate and dimethallylorthophthalate, -azelate and -tetrachlorophthalate. Specifications 572,858 and 687,295 are referred to.
