    摘要: The present invention provides shaped articles comprising one or more composite layer of (i) a vulcanizate encapsulated in a colored or uncolored thermoplastic polymer matrix containing one or more passivating agent, and (ii) a reflective material chosen from colored fluidizable particles of a thermoplastic reflective colorant encapsulated vulcanizate, roofing granules, thermoplastic encapsulated roofing granules, the colored thermoplastic polymer matrix, and combinations thereof. The articles can be laminates of colored or reflective layers on uncolored or other layers, or one or more colored layer having colored fluidizable particles are dispersed within the surface of the uppermost composite layer or having either the colored fluidizable particles or the granules are dispersed on the surface of the composite layer or are adhered thereto with a thermoplastic resin. Roofing shingles are provided.

    摘要: The present invention provides methods for making shelf-stable fluidizable particles that comprise mixing from 35 wt. % to 89.95 wt. %, based on total solids, of particles of one or more vulcanizate having a sieve particle size of from 10 to 800 μm, 10 to 65 wt. %, based on total solids, of one or more thermoplastic polymer in the form of an emulsion of a thermoplastic polymer in the presence of from 0.05 to 3 wt. %, based on total solids, of a passivating agent, to form a moist mixture followed by drying the moist mixture to form fluidizable particles such that the total solids content of the mixture remains 65 wt. % or more throughout processing. In addition, the invention provides plasticizer free storage stable fluidizable particles and 0colored fluidizable particles.
