Abstract
Thermoplastic elastomeric compositions and processes for preparing the compositions comprising a blend of polypropylene, styrene-ethylene butylene-styrene copolymer, ethylene-propylene-diene monomer elastomer, linear low density polyethylene, peroxide crosslinking agent and a crosslinking coagent. The peroxide crosslinking agent and crosslinking coagent provide a crosslinking system. The compositions improve melt strength and increase resistance to flow and tear. The composition may further comprise mineral oil, antioxidant, colorant, a processing aid and stabilizer and mixtures thereof. The processes for preparing thermoplastic elastomeric compositions are particularly useful in microcellular injection molding to form articles with improved surface characteristics.
