Abstract

551,120. Synthetic resins. DU PONT FILM MANUFACTURING CORPORATION. Aug. 1, 1941, No. 17111/42. Convention date, Aug. 1, 1940. Divided out of 551,117. [Class 2 (iii)] [Also in Group XX] The polyvinyl acetal of 3:5-dichlorsalicylaldehyde-o-benzaldehydesulphonic acid is made from the aldehydes and polyvinyl alcohol by the method of Specification 535,341. A coating solution is made by dissolving the acetal in dimethyl formamide, ethyl alcohol, and water, with a little caustic soda to make the solution neutral. Symm. bis-(m-(5-keto-3-methylpyrazyl)-phenyl) -urea-formaldehyde resin is made by reacting maminophenyl-3-methyl-5-pyrazolone with phosgene, and reacting the product with formaldehyde.
