Abstract

328,728. I. G. Farbenindustrie Akt.- Ges. Dec. 24, 1928, [Convention date]. Ester condensation products.-Synthetic resins are prepared by condensing adipic acid or its higher homologues containing a branched chain with a polyhydric alcohol, with or without a mono or dibasic carboxylic acid. The products are very plastic, and may be added to phthalic and glycerin resins to produce flexible products. As additional acids oleic and resin acids are mentioned. In the examples, (1) adipic acid and glycerin are heated at 160‹-165‹ C. for several hours, the A-resin thus formed being converted into the C-form by further heating at 160‹-180‹ C.; (2) a mixture of isomeric methyl adipic acids is heated with glycerin and boric acid at 160‹ C. Specification 317,225 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes the use of other aliphatic polybasic acids having six or more carbon atoms, such as sebacic acid instead of adipic acid. This subject-matter does not appear in the Specification as accepted.
