Abstract: The present invention is related to novel acid functional pigment dispersing agents. In particular, the invention is directed to novel polymers with acid functional groups for use as pigment dispersants. The novel polymers comprise polymeric amides with free carboxyl functional groups having the structure: wherein PE is a polyester, PA is a polyamine and A is an anhydride. The novel pigment dispersants of the present invention are particularly effective for the dispersion of high color carbon black and organic pigments. The advantages of the novel pigment dispersants over known amine functional polymeric dispersants are several. They do not tend to discolor when exposed to UV light. They do not inhibit acid catalyzed reactions such as melamine crosslinking or react with isocyanate or catalyze the isocyanate/H2O reaction. They are non-toxic or much less toxic to aquatic organisms.

Abstract: The invention relates to acrylated chlorinated rubber, a method for making acrylated chlorinated rubber comprising reacting chlorinated hydroxyrubber and acryloyl chloride with triethylamine as a catalyst, and photocurable rubber coatings comprising acrylated chlorinated rubber.

Abstract: A metal (M) alkyl acid phosphate catalyst for the reaction of an epoxy compound with a carboxyl compound to provide a coating formulation that is stable at room temperature; that is humidity resistant, and non-yellowing, wherein the alkyl acid phosphate has the formula: (RO)n—(P═O)—(OH)m and wherein: a. each R is selected from the group consisting of: i) a C1 to C18 alkly, cycloalkyl, or aryl; ii) a linear or branched C6 to C18 alkyl substituted with —(O—CH2—CH2—)o or —(O—CH—CH3—CH2—)p, wherein o or p is from 1 to 20; iii) a &bgr;-hydroxyethyl compound, R′—X—CH2—CH—OH—CH2—, wherein R′ is a C6 to C18 alkyl or cycloalkyl or aryl, X is either —CH2—, —O— or —COO—; b. n+m=3 and n is between 2 to 1; and c. M is Zn or Sn (II) in a mole equivalent of 0.7 to 1.5 moles per mole of alkyl acid phosphate.

Abstract: The present invention is directed to novel metal organocomplexes as catalysts for the reaction of compounds with isocyanate and hydroxy functional groups to form urethane and/or polyurethane and the process employing such catalysts. More particularly, the present invention is directed to novel complexes of zirconium or hafnium with diketones or alkylacetoacetoates. These novel catalysts are useful for the production of urethanes and polyurethanes which are important in many industrial applications, such as: coatings, foams, adhesives, sealants, and reaction injection molding (RIM) plastics.
