Abstract: The invention concerns substance mixtures containing: (A) compounds containing vinyl groups; (B) an active amount of a mixture which inhibits premature polymerization of the compounds containing vinyl groups and contains: (i) at least one N-oxyl compound of a secondary amine which does not carry any hydrogen atoms on the alpha -carbon atoms; and (ii) at least one iron compound; (C) optionally nitro compounds; and (D) optionally co-stabilizers. The invention further concerns a process for inhibiting the premature polymerization of compounds (A) containing vinyl groups, and the use of mixture (B), optionally mixed with nitro compounds (C) and/or co-stabilizers (D), for inhibiting the premature polymerization of radically polymerizable compounds and for stabilizing organic materials against the harmful effect of radicals.

Abstract: Production of microcellular polyurethane elastomers is claimed by reacting (A) high mol. polyhydroxy compounds and optionally (B) low. mol. chain extenders and/or crosslinkers with (C) 3,3'-dimethoxy-4,4'- diisocyanato-diphenyl in presence or absence of (D) catalysts, foaming agents etc.. Preferably the polyhydroxy component (A) is of functionality 2-3 and mol. wt. 500-6,000 and is especially a difunctional polyester polyol, OH-containing polycarbonate or polyoxybutylene glycol of mol. wt. 800-3,500 while the chain extender is an alkane diol, dialkylene glycol or polyoxyalkylene glycol of mol. wt. up to 800 and the crosslinker is also of mol. wt. up to 800 and is a tri-or tetra-hydric alcohol or polyoxyalkylene polyol of functionality 3-4. Preparation of the elastomer is by: (1) first preparing a prepolymer of NCO content 2-20 wt.% by reacting (C) with (A) and optionally (B) and then reacting this prepolymer with water and optionally also (B); or (2) first reacting (C) with part of (A) and optionally also (B) and then reacting the prepolymer obtained with a mixture of water, the remainder of (A) and optionally also (B).
