Abstract
An anti-environmental stress cracking additive particle, wherein the particle may include an anti-environmental stress cracking active phase, a support phase, and a compatibilizing phase, and wherein the particles have an average size of up to 200 μm. Processes for preparing the anti-environmental stress cracking additive may include a solvent/non-solvent process, a free non-solvent process, and solid state methods. A polymer composition may include a matrix polymer and the anti-environmental stress cracking additive. An article may comprise the polymer composition comprising the anti-environmental stress cracking additive particle.
