Abstract: The present invention relates to trimellitic anhydride imide ester, a method of making it, and polyesters or polyamides that can be modified with trimellitic anhydride (TMA) to provide better heat resistance and mechanical properties. With the present invention, there are two processes for making TMA-ester. The first process is by charging into a reactor equimolar amounts of trimellitic anhydride and primary hydroxyalkylamine, primary carboxylalkylamine or primary carboxylarylamine, with an excess of alcohol or diol. The second process for producing the imide ester is to react two moles of TMA with one mole of a diamine of the formula H2N—X—NH2 with an excess of alcohol or diol; where X is an aliphatic, alicyclic, or aromatic group. Generally the reactor contains water as a dispersant for the reactants. The reaction time is from about 1-8 hours. The reaction temperature is from about 160° C. to about 220° C.

Abstract: Hot-melt adhesives based upon a mixture composed of poly(vinylmethylether), greater than about 10 weight percent of a thermoplastic resin and, optionally a tackifier resin and/or extender, are found to be superior for the binding of polyolefins such as polyethylene, polypropylene, and ethylene-propylene copolymers to themselves and to other substrates. In particular, the hot-melt adhesives are useful for bonding polyethylene-backed and latex-backed carpet to polyethylene, polypropylene, or ethylene-propylene copolymer.

Abstract: A regiospecific, catalyzed process for preparing acyl derivatives of aromatic nitrogen-containing heterocyclic compounds in which the keto group is selectively added ortho to the nitrogen atom on the aromatic ring. In the presence of a ruthenium carbonyl compound, carbon monoxide and an olefin, the aromatic heterocyclic compound which has an unsubstituted carbon atom ortho to at least one of the heterocyclic atoms adds the acyl group essentially completely in ortho position.

Abstract: A polymer having pendant silyl ether groups is disclosed having a minimum solubility parameter of 6.85 (cal/cc).sup.1/2 or less. That minimum solubility parameter is reduced to 6.85 (cal/cc).sup.1/2 or less by control of the number of pendant silyl ether groups and by the selection of said silyl ether groups. The polymer can be formed by reacting a olefin monomer with a silyl monomer or by grafting a silyl monomer onto an unsaturated polyolefin. Preferably, the silyl monomer is either a vinyl trimethylsilyl ether monomer, a vinyl dimethylchlorosilane monomer, or a vinyl methyldichlorosilane monomer. Preferably, the olefin monomer is decene, and the unsaturated polyolefin is polydecene.
