Abstract: The present invention provides solvent- and water-based primer compositions that include at least one carboxylated polyolefin that has been modified with one or more polyfunctional alcohols. The carboxylated polyolefins are obtained by the reaction of polyolefins with at least one of unsaturated carboxylic esters, unsaturated carboxylic acids, unsaturated carboxylic anhydrides, acrylic monomers, and mixtures thereof. The carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols. These polyfunctional alcohol-modified polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines or inorganic bases, thereby rendering the polyfunctional alcohol-modified polyolefins water-dispersible. These primer compositions are useful for significantly improving the adhesion of paints, adhesives, and inks to various plastic and metal substrates.

Abstract: The present invention provides solvent- and water-based primer compositions that include at least one chlorinated carboxylated polyolefin that has been modified with one or more polyfunctional alcohols. The chlorinated carboxylated polyolefins are obtained by the reaction of polyolefins with at least one of unsaturated carboxylic esters, unsaturated carboxylic acids, unsaturated carboxylic anhydrides, acrylic monomers, and mixtures thereof then chlorinated. The chlorinated carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols. These polyfunctional alcohol-modified chlorinated carboxylated polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines or inorganic bases, thereby rendering the polyfunctional alcohol-modified chlorinated carboxylated polyolefins water-dispersible.

Abstract: The invention relates to a process for purifying and decolorizing a phenyl ester salt. The process combines a phenyl ester salt with a solvent to form a mixture and then stirs the mixture to form a slurry. The phenyl ester salt is substantially insoluble in this solvent. The process then collects the phenyl ester salt from the slurry. The collected phenyl ester salt may then be optionally dried or recrystallized. The collected phenyl ester salt is dissolved in a solvent to form a solution. The solution is decolorized and then spray dried to form a powder of the phenyl ester salt. As a result of the process the phenyl ester salt powder has a higher purity and an improved color as compared to the starting phenyl ester salt.

Abstract: The invention enables solution modification of a polyolefin with an unsaturated anhydride, unsaturated acid, or unsaturated ester, with high efficiency without the formation of undesirable impurities resulting from the competing reaction of the solvent with the unsaturated anhydride, unsaturated acid, or unsaturated ester. The process entails combining a polyolefin; a solvent; an unsaturated anhydride, unsaturated acid or unsaturated ester and a free-radical initiator to form a reaction mixture. The solvent is selected from the group consisting of substituted aromatic solvents which do not contain benzylic hydrogens and mixtures thereof. This reaction mixture is reacted under suitable conditions to produce a modified polyolefin.
