Abstract

944,309. Uretedione derivatives. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 6, 1962 [June 16, 1961], No. 21840/61. Addition to 821,158. Heading C2C. The invention comprises dimeric tolylene-2,6- diisocyanate (viz. N,N<SP>1</SP>-bis (3-isocyanato-2- methylphenyl)uretedione) and mixture thereof with dimeric tolylene-2, 4-diisocyanate. The compounds are prepared by polymerizing tolylene-2, 6-diisocyanate, or a mixture thereof with tolylene-2, 4-diisocyanate, using the process claimed in Claims 1, 2, 3, 5, 6 and 7 of the parent Specification.
