Cyclocopolymerization of 2,4-tolylene diisocyanate with 1,6-hexamethylene diisocyanate in the presence of sodium diethyl phosphite: Cyclocopolymerization of 2,4-tolylene diisocyanate with 1,6-hexamethylene diisocyanate in the presence of sodium diethyl phosphite. Zainutdinova, L. Sh.; Bakhitov, M. I.; Kuznetsov, E. V. (Kazan. Khim.-Tekhnol. Inst. im. Kirova, Kazan, USSR). Fiz.-Khim. Osn. Sint. Pererab. Polim., 1, 16-17 (Russian) 1976. CODEN: FOSPDL. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) A copolymer (I) [63368-95-6] contg. 1,3,5-triazine [290-87-9] rings was obtained by cyclopolymn. of 2,4-tolylene diisocyanate [584-84-9] with hexamethylene diisocyanate [822-06-0] in the presence of (EtO)2PONa [2303-76-6] catalyst. Formation and structure of I was demonstrated by DTA, turbidimetric titrn., and IR spectroscopy. The rates of the cyclopolymn. were faster in cyclohexanone than in benzene solns.
