Abstract: The present invention consists of materials and a processing method for coating rigid-rod poly(ionomers) or salts thereof, in a solvent system, directionally on charged surfaces resulting in the formation of liquid crystal display surfaces with planar alignment and pretilt.

Abstract: A liquid microemulsion stabilizer for chlorinated polymers composition for stabilizing halogen-containing polymer comprising: a) a microemulsion of an overbased metal carbonate/carboxylate obtained from the reaction of an oxide and/or hydroxide of a metal selected from the group consisting of sodium, potassium, calcium, magnesium, zinc and mixtures thereof, an aliphatic carboxylic acid in which the aliphatic moiety contains up to about 30 carbon atoms and carbon dioxide in the presence of a solvent for the aliphatic carboxylic acid, a promoter and a microemulsion-forming amount of surfactant; and, b) an organotin stabilizer.

Abstract: A method is disclosed for stabilizing a halogen-containing polymer wherein the method comprises adding to said polymer a thermally stabilizing amount of a mixture comprising at least one polyalkylene glycol and at least one metal salt of a strong acid selected from the group consisting of perchloric acid, trifluoroacetic acid, trifluoromethanesulfonic acid, alkylsulfuric acid, phosphotungstic acid, HPF6, HBF4, and HSbF6

Abstract: A process for making a product containing tin (II) carboxylates of the formula (RCOO)2−n(OOCR′)n, where each R, which may be the same or different, is hydrogen or a C1-C40 hydrocarbyl group, each R′, which may be the same or different, is a C1-C40 hydrocarbyl group, and n is 0, 1, or 2 the process comprising: (a) forming a reaction mixture by combining elemental tin, a promoter, and one or more carboxylate-containing compounds of the formula R(CO)X, where R is hydrogen or a C1-C40 hydrocarbyl group and X is a hydroxyl group, a halogen atom, or O(CO)R′, where R′ is a C1-C40 hydrocarbyl group; (b) heating the reaction mixture to form heated reaction mixture; (c) oxidizing the heated reaction mixture using an oxygen-containing gas to form an oxidized reaction mixture containing tin (II) carboxylates as well as tin (IV) carboxylates; and (d) reducing the oxidized reaction mixture with elemental tin to convert at least a portion of the tin (IV) carboxylates to tin (II) carboxylate

Abstract: Disclosed are polymeric plasticizers of the formula (1)R.sup.a --C(O)--(O--G--OC(O)--(CH.sub.2).sub.4-12 --C(O)).sub.1-12 --O--G--O--C(O)--R.sup.b (1)wherein R.sup.a and R.sup.b are each C.sub.2 -C.sub.22 straight saturated alkyl groups, and wherein each G group is 1,2-propanediyl or 2-methylpropane-1,3-diyl such that both types of G groups are present in a ratio to each other of 3:1 to 1:3.

Abstract: An overbased mixture of aliphatic and aromatic carboxylates salts useful in making low-fogging thermal stabilizers for PVC is made by reacting zinc oxide with fatty acid and such as stearic acid, then adding aromatic acids, and then adding and reacting one or both of magnesium oxide and calcium oxide, under controlled heating conditions to maintain fluidity while minimizing side reactions, and then conditioning the reaction product to remove volatiles.

Abstract: Liquid polyvinyl chloride resin stabilizer systems are provided, based on complexes of organic triphosphites with zinc chloride, and, in addition, other compatible polyvinyl chloride resin stabilizers, including particularly, thiophosphites of mercaptocarboxylic acid esters, as well as barium-cadmium and barium-zinc carboxylic acid salt combinations, and liquid barium carbonate-alkyl phenate complexes.

Abstract: Novel peroxydicarbonates are provided in which the alkyl carbonate moiety is 2-alkyl-2-phenyl substituted. The compounds are useful as polymerization initiators of ethylenically unsaturated monomers, such a vinyl chloride, and as catalysts of unsaturated polyester resins. The subject peroxydicarbonates are characterized in that they are solid at room temperature, have ambient temperature stability in spite of a low 10 hour half-life temperature, and can normally be transported and stored without refrigeration.
