    Abstract: The present invention provides compositions for use as elastomeric roof coatings having excellent infrared (IR) reflectivity which comprise (i) one or more elastomeric copolymer having a measured glass transition temperature (measured Tg) of from −100 to 0° C. and one or more mesoporous filler, preferably a mesoporous filler that is substantially free of organic groups or residues, the mesoporous filler chosen from mesoporous silica, mesoporous aluminosilicates and mesoporous alumina, wherein the composition has a pigment volume concentration (% PVC) of from 0.1 to 15%. Such compositions provide aqueous or solvent borne clearcoats that can go over existing, already painted or colorcoated roof or wall substrates to preserve their finish or appearance.

    Abstract: A process for separating and recovering at least one polymer component from a melt of a multiple number of polymer components including the steps of: (A) shearing a multi-polymer component melt in the presence of a pressurized aqueous solution; wherein the multi-polymer component melt comprises a blend of at least a first polymer component and at least a second polymer component; wherein the multi-polymer component melt has at least two melting temperatures, at least two glass transition temperatures or combinations thereof; wherein the pressurized aqueous solution comprises an aqueous liquid mixture of: (i) water, and (ii) at least one dispersing agent; wherein the shearing of the multi-polymer component melt in contact with the pressurized aqueous solution forms a dispersion, particles, or strands of the at least one first polymer component having an enriched first polymer component concentration; and (B) after the shearing of step (A), isolating the at least first polymer component from the other polymer components of the multi-polymer component melt by separating the dispersion, particles, or strands of the at least one first polymer component having an enriched first polymer component concentration from the water, the at least one dispersing agent, the at least second polymer component, and any remaining thermoplastic polymer resins present in the mixture of the multi-polymer component melt in the pressurized aqueous solution.
