    Abstract: Low creep. impact-resistant palymerizates of olefinic nitriles, useful as gas and vapor barriers, were prepd. by polymerizing an ester of an olefinically unsatd. acid (CH2 = CR1-COOR2; R1 = C1-4 alkyl group or halogen, R2 = C1-6 alkyl group) and indene in the presence of a rubber prepd. from a conjugated diene and an olefinically unsatd. nitrile (CH2 = CR-CN ; R4 = C1-4 lower alkyl or halogen group).

    Abstract: The β-cryst. form of TiC14 was combined with Et2A1C1 and an org. ether to give a brown solid having surface area >50 m2/g and pore vol. >0.10 cm3/g. The brown solid led to improved polmn. rates and yields in the polymn. of α-olefin (esp. propen). Thus, 74.8ml Et2A1C1 in hexane was reacted with 12.5ml TiC14 and hoxane. Hexane and 21.3ml isopentyl ether were reacted for 2hr at 65oC after 70.8ml TiC14 in hexane (20.3% soln.) were added. 3rd decantation gave 0.295g brown solid.

    Abstract: Catalysts(I) for oxidn. of (meta)acrolein to (meta) acrylic acid at 200-500≦̸C with improved selectivity contain oxides or oxide complexes of Ce, W,V, Mo, and optionally, Fe, Co, Ni, Zr, Cu, Mg, Mn, Bi, Ti, Zr, Sn, P, transition, alkali, alk. earth, or lanthanide metals. I also was very useful for oxidn. of butadien to maleic anhydride and oxidn. esterification of usatd. aldehyde to corresponding unsatd. polyester.

    Abstract: Graft acrylonitrile-butadiene-indene polymer, having good impact resistance, low permeability to gases, and high softening temp., was prepd. by grafting acrylonitrile and indene on nitrile rubber. Thus, an aq. emulsion of acrylonitrile 70, indene 17.5 and rubber latex 15 parts was polymd. at 60≦̸C for 6hr using K2S2O8 as catalyst and limonene dimercaptane, and then the reaction mixt. was heated to 70≦̸C and K2S2O8 0.2, indene 12.5 and limonene dimercaptane 0.5 part were added over a period 5hr to give I.

    Abstract: Maleic anhydride(I) was manufd. from butane by oxidn. over catalysts of high life and of the type VaPbVcOx (a,b = 0.1-10, c = 0.01-5, X = Numbers of O atom which satisfy the atomic value of other atoms) Thus, 33.6g V2O5 in 438ml concentrated HCl was treated with 31.3g VO2(C2H3O2) 2HO2, refluxed 1hr, treated with H3PO4, refluxed, dried, and used at 482≦̸C to prepare I in 47-50% yield from a 1:100 butane air mixt.

    Abstract: High-mol. polymer, useful as protective enamel for elec. wire, was prepd. from trimellitic anhydrides, trimellitic aromatic or aliphatic diamine and diisocyanate. Thus, trimellitic anhydride or tirmellitic acid and primary diamine with 1:0.7-0.9 mole ratio were condensed at 210-250≦̸C to give low mol. anhydride. This polymer was condensed with diisocyanate with 0.1-0.3 mole (max. 0.75 mole) per anhydride at 25-150≦̸C in inactive solvent to give high mol. polyamide-imides.

    Abstract: Novel copolymers and terpolymers of the amide-imide type are prepared from tricarboxylic acid anhydride compounds, N,N'-diacylated diamines, N-acylated diamines, and primary diamines. These copolymers and terpolymers are useful for preparing injection molded articles of superior properties. A novel process for the manufacture of amide-imide copolymers and terpolymers is disclosed wherein the imide, imide-imide, amide, and amide-amide moieties incorporated into the polymer backbone can be controlled by acylating the amine functionality which is to form the amide and amide-amide moieties while reacting directly those diamines with a tricarboxylic anhydride compound which are intended to form the imide and imide-imide moieties.
