ABSTRACT:
Thermoplastic elastomer blends comprising a thermoplastic elastomer and 1-20% by weight of a water insoluble alkyl cellulose exhibit improved mechanical properties compared to the unblended thermoplastic elastomer. The preferred thermoplastic blend of end polypropylene elastomer is EPDM. The preferred concentrations are 2.5-15%, most preferably 5-12%, all percentages being by weight based on total polymer content. The blends are formed by high shear mixing at a temperature at which both materials are melt processible. The alkyl cellulose in the product is present as domains which are essentially uniformly dispersed in a thermoplastic elastomer matrix.
