    摘要: A polyol composition consisting essentially of a homogenous liquid admixture of propylene glycol and a diol obtained by alkoxylating a propylene glycol dispersion of 3,3',5,5'-tetrabromobisphenol A with ethylene oxide, propylene oxide or mixtures thereof. These polyol compositions are useful in preparing fire and chemical resistant thermosetting resinous compositions.

    摘要: Disclosed are tertiary amine oxides which comprise an amine oxide nucleus substituted with an organic group and with two hydroxy groups which have carbon atoms in at least the .alpha., .beta. and .gamma. positions, a hydroxyl group on the .beta.-carbon atom, and have an effective chain length of at least 4 carbon atoms, said amine oxide being capable of being provided in ostensibly anhydrous form and being capable of being made at a concentration by weight of at least about 80% by oxidizing the corresponding tertiary amine with an oxidizing agent without solvent and without gelling during said oxidation.
