Abstract: The present invention is a waterborne coating composition comprising a hydrophobically modified emulsion polymer and a process therefore. The emulsion polymer is formed by first combining hydrophobic polymeric compound and .alpha.,.beta.-ethylenically unsaturated monomer, to form a mixture and subjecting the mixture to high stress techniques to form surfactant stabilized particles of the hydrophobic polymer and monomers, in the aqueous phase. The .alpha.,.beta.-ethylenically unsaturated groups within the particles are co-polymerized to form a hydrophobically modified core polymer. Additional monomers including at least one .alpha.,.beta.-ethylenically unsaturated hydrophilic monomer are then added to the core polymer and polymerized by emulsion polymerization, to form a hydrophobically modified emulsion polymer. To form a coating composition, additional components such as pigments, crosslinkers, plasticizers and solvents are added. The coating is applied to a substrate to form a coated article.

Abstract: Systems and methods are provided whereby additive for thermoplastic materials may be recovered in a primary additive supply system simultaneously with the supply of an additive from a secondary additive supply system to a molten thermoplastic stream. Each of the primary and secondary additive supply systems is provided with respective recirculation lines so as to prevent sedimentation of the additive. According to the present invention, therefore, a protocol is employed whereby substantially all of the additive in the additive supply system, including that quantity of additive in the recirculation lines, may be recovered so that a fresh supply of additive (which oftentimes is different from the previous additive) may be connected for injection into the molten thermoplastic stream at the appropriate time.
