摘要： The invention relates to the preparation of N-.alpha.-alkoxyethyl-carboxylic acid amides from dimethyl acetal and a carboxylic acid amide such as acetamide and to the preparation of secondary N-vinyl carboxylic acid amides such as N-vinyl acetamide therefrom.The reaction of dimethyl acetal and the carboxylic acid amide involves an equilibrium disproportionation wherein excess dimethyl acetal is used in sufficient amounts, e.g., in a molar ratio of from about 2 to 60:1 mole ratio, so as to force the equilibrium to the desired N-.alpha.-alkoxyethyl-carboxylic acid amide intermediate product. Equilibrium is reached in about 0.1 to 150 hours at a temperature about 0.degree. to 100.degree. C. The intermediate N-.alpha.-alkoxyethyl-carboxylic acid amide is pyrolyzed in accordance with a known pyrolysis reaction so as to obtain the corresponding N-vinyl acetamide.

摘要： A process for preparing certain halogenated aromatic polyesters having a predetermined molecular weight is provided. Such polyesters are prepared by solution polymerization of an appropriate bisphenol and diacid halide wherein the diacid halide is added to a solution containing the bisphenol until the viscosity of the resulting polymer containing solution reaches a predetermined solution viscosity limit at which time the further addition of diacid halide is terminated. The solution viscosity limit is indicative of the attainment of said predetermined molecular weight. The identification of said solution viscosity limit is achieved by a feedback mechanism wherein the viscosity of the polymer containing solution is monitored or sensed during or after the addition of the diacid halide to the bisphenol containing solution.

Cellulose acetate and cellulose triacetate fibers and films containing as little as two percent by weight of the polymeric flame retardant additives are rendered both non-burning and resistant to loss of the polymeric flame retardant additive during use.

摘要： A substituted polybenzimidazole polymer is disclosed wherein sulfoalkyl derivatives of polybenzimidazole are produced by the reaction of a polybenzimidazole polymer with a sultone. Beta sultones may be directly reacted with the polybenzimidazole polymer to produce a sulfoethyl derivative of polybenzimidazole. However, when gamma, delta or eta sultones are used, the polybenzimidazole polymer preferably is first reacted with an alkali hydride to produce the polyanion of polybenzimidazole. The polybenzimidazole polyanion is then reacted with the sultone to produce a sulfoalkyl derivative of polybenzimidazole polymer. These derivatives may find great use as ion exchange devices or for reverse osmosis or ultrafiltration devices.
