Abstract: The present disclosure relates to a method for the emulsion polymerization of itaconic acid containing ester functionality, for example, the alkyl esters of itaconic acid known as alkylitaconate. More specifically, an ester of polyitaconic acid polymer is produced via emulsion polymerization and contains greater than 50% by weight of an ester of itaconic acid along with a selected particle size and levels of molecular weight and syndiotactacticity.

Abstract: Embodiments of the present invention involve printing members that utilize a particle-fusion imaging mechanism but avoid susceptibility to handling damage. In particular, printing plates in accordance with the invention may utilize two phases, and these may originate, during manufacture, as two particle systems. Both systems are initially dispersed in a single coating applied as a layer, or in multiple coatings applied as adjacent layers, on a substrate. The second particle system exhibits a glass-transition or thermal coalescing temperature well above room temperature and also above the temperature at which the coating is dried. The coalescing temperature of the first particle system is below the drying temperature. As a result, when the coating is dried, the first particle system coalesces and forms a binder that entrains the second particle system, which has not coalesced.

Abstract: Agglomerated hollow particle latex is employed as a filler in the wet end of the paper-making process to provide paper with improved properties.

Abstract: Flexible polyurethane foams are prepared by reacting a polyisocyanate with a high equivalent weight polyol. At least a portion of the high equivalent weight polyol is a polyester containing hydroxymethyl groups. The polyester is prepared in a multi-step process from animal or vegetable fats, by recovering the constitutent fatty acids, hydroformylating carbon-carbon double bonds in the fatty acids and reducing to form hydroxymethyl groups, and then forming a polyester by reaction with an initiator compound.

Abstract: Polyols useful in the manufacture of polyurethanes are disclosed. The polyols are prepared by reacting a vegetable oil based (hydroxymethyl containing) monomer with a polyol, polyamine or aminoalcohol under vacuum.

Abstract: A distinctive graft copolymer is made by dissolving an unsaturated polyester resin in various vinyl monomers (methyl methacrylate, styrene, etc.). The monomer/unsaturated polyester solution is then miniemulsion polymerized to form a latex consisting of submicron particles of polymer with the polyester grafted onto the polymer backbone. The latex can be applied to a substrate, which on drying forms a polymeric film with good film properties. The latex can be used in a latex paint formulation in place of an acrylate, acetate or styrene-divinyl benzene latex. In this way it is possible to produce water-borne unsaturated polyester coatings which combine the film hardness properties of an unsaturated polyester coating with easy application and cleanup. The coating will beneficially lack organic solvent exposure of typical polyester coatings.
