摘要： The present invention is directed to improved flexibilized, plasticized polyvinyl chloride films bonded with a substrate by means of an aqueous based pressure sensitive acrylic adhesive emulsion polymers. Conventional emulsion based pressure sensitive adhesives were comprised of a copolymer comprised of polymerized units of acrylic esters and ethylenically unsaturated monomers, the copolymer having a Tg of from −15 to −70° C. The improvement in the aqueous based, emulsion polymerized pressure sensitive adhesives resides in the incorporation of polymerized units of a vinyl C8-13 ester of a neo-acid into the adhesive. The vinyl ester is formed from a mixture of propylene oligomers and such vinyl ester is represented by the chemical formula: C8-13H7-27CO2CH═CH2. Preferably, the adhesive includes units of methyl methacrylate, butyl acrylate of 2-ethylhexyl acrylate and a carboxylic acid selected from acrylic acid or methacrylic acid.

摘要： Vinyl naphthenate monomer mixtures are prepared by transvinylation of naphthenic acid in the presence of a catalyst of a palladium carboxylate complexed with one or more aryl N-containing ligands and distilling the resulting vinyl naphthenate monomers in the presence of the catalyst at pot temperatures exceeding 80.degree. C. The catalyst is stable and can be re-used over several transvinylation reaction runs.

摘要： This invention relates to a process for producing an aminoalkylal derivative of polymer containing a plurality of polymerized vinyl alcohol units which are vicinal, preferably a process for producing the 4-aminobutyral of poly(vinyl alcohol). The improved process for the amino-acetalization of such polymers described herein comprises reacting a 5 of 6 member cyclic imine of the structure ##STR1## wherein n is an integer from 3 to 4 with the polymer containing a plurality of polymerized vinyl alcohol units. In a preferred reaction, 1,2-pyrroline is reacted with the polymer containing polymerized vinyl alcohol units under acidic conditions. Preferably the reaction is carried out by a slurry phase process employing a non solvent carrier such as methanol for the poly(vinyl alcohol). The reaction scheme for preparing the 4-aminobutyral of poly(vinyl alcohol) may be characterized by the following equation. ##STR2##
