Claim:
1. A method for preparing composite particles, the method comprising: melt blending one or more non-elastomeric organic polymers, each having a glass transition temperature of at least 40° C. and up to and including 120° C. as measured using differential scanning calorimetry at a scanning rate of 20° C./minute, with a plurality of multi-compartment porous chemically crosslinked elastomeric particles that have a mode particle size of at least 1 μm to and including 10 μm, wherein the non-elastomeric organic polymer comprises a polyester, styrene-acrylic copolymer, cellulosic polymer, polyamide, polyimide, vinyl ester polymer, mono-olefin polymer, vinyl ether polymer, vinyl ketone polymer, or a polymer formed from one or more α-methylene aliphatic mono-carboxylic acid esters, to form a composite blend, and grinding the composite blend to form composite particles,
