    Abstract: Viscous polybutenes of number average molecular weight (Mn) in the range of about 300 to about 3,000 have improved reactivity with intramolecular anhydrides of unsaturated aliphatic dicarboxylic acids when such polybutenes contain rather small amounts, i.e., 5 to 200 ppm, of brominated dialkylhydantoin. Preference is given to such bromine containing compounds having a sufficient vapor pressure at a temperature in the range of 100* to 300*C. to be substantially completely removed at absolute pressures in the range of 5 to 760 mm Hg. Use of such polybutenes containing such brominated compounds in the addition reaction with said unsaturated anhydrides can reduce formation of undesired tarry product resulting from polymerization and/or thermal decomposition of the unsaturated anhydrides and enhance yield of desired alkenyl-substituted anhydride.

    Abstract: Novel title esters are oil-soluble products derived from mono-, di-, tri- and higher hydric alcohols and hydroxy aromatic compounds reacted with 4-(C30-C214 alkyl-substituted carbophenoxy) phthalic anhydride or its diacid. Title esters are useful addition agents for lubricants to impart thereto antiwear, anti-rust and dispersancy functions.

    Abstract: Novel urethane derivatives of polymethyl biphenyl useful as fungicides and also having insecticidal, miticidal and nematocidal activities are disclosed. These products are prepared by reacting the appropriate alkyl or aryl chloroformate with the appropriate amino polymethylbiphenyl at temperatures of 0 to 35*C. to produce the corresponding urethane derivatives of polymethyl biphenyl.
