    摘要: Methacrylamidopropyltrimethylammonium chloride or its free amine, dimethylaminopropylmethacrylamide, is purified by contacting aqueous solutions of the salt or the free amine with solid, nonionic organic resins. Such resins absorb the organic impurities, yet leave behind the polymerization inhibitor.

    摘要: Disclosed is an ethylene glycol based deicing/anti-icing composition which contains a thickener comprising a polyacrylic acid having a molecular weight of from about 90,000 to 100,000 and a wetting agent from the group consisting of nonylphenol ethoxylates, alkarylsulfonates, polyoxyethylene phosphates and tetrafunctional block copolymers of EO/PO on an ethylene diamine backbone and demonstrates improvement in anti-icing ability as measured by holdover time while not adversely effecting aerodynamic performance or Newtonian rheology of the deicer measured by passing the minimum requirements of the AMS test for Type I fluids.

    摘要: Novel compounds made from the reaction of 5-vinyl-2-norbornene with carboxylic acid anhydrides in the presence of oxygen are described. The process to make these novel esters is preferably conducted at a temperature in the range from about 50.degree. to 150.degree. C. and in the presence of a catalyst. A transition metal borate catalyst is preferred. Such ester compounds are potentially useful plasticizers, lubricants, solvents and fuel additives.
