Principles of the interaction of macrodiisocyanates with components of SKEPT rubbers

Principles of the interaction of macrodiisocyanates with components of SKEPT rubbers. Nikolaev, V. N.; Izheeva, M. M.Chemicals with cas numbers 25322-69-4 and 584-84-9 also play role.; Kirillova, V. T. (Chuvash. Gos. Univ., Cheboksary, USSR). Kauch. Rezina, (3), 15 (Russian) 1984. CODEN: KCRZAE. ISSN: 0022-9466. DOCUMENT TYPE: Journal CA Section: 39 (Synthetic Elastomers and Natural Rubber) A macrodiisocyanate (I) (prepd. from polypropylene glycol and 2,4-TDI) reacted with SKEPT-40 rubber only in the presence of p-dinitrobenzene (II) [100-25-4] activator to give 88.3-95.2% gel fraction. No reaction occurred in the presence of Captax. .

Nauk SSSR, 232(5), 1088-91 [Chem.] (Russian) 1977. CODEN: DANKAS. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 25 Arom. diisocyanate were obtained in 32-75% yields by carbonylation with CO of the corresponding dinitro compds. at 210.degree. and 300 atm in the presence of a heterogeneous catalyst consisting of PdO-MoO3-Fe2O3 (2-6:1:1) on .gamma.-Al2O3 support. The reactivity of the dinitro compds. decreased in the sequence: m-dinitrobenzene [99-65-0] < 2,4-dinitrotoulene [121-14-2] < 1,3-dimethyl-4,6-dinitrobenzene [616-72-8] .apprx. dinitromesitylene [608-50-4] < 1,4-dinitrobenzene [100-25-4] .apprx. 3,6-dinitro-1,2,4,5-tetramethylbenzene [5465-13-4]. .
