Polyolefin-based resin composition for vehicle interior material comprising heat-treated waste coffee grounds

Disclosed is a polyolefin-based resin composition for a vehicle interior material including heat-treated waste coffee grounds. The resin composition includes a polyolefin-based resin, waste coffee grounds including a volatile matter (VM) in an amount less than about 20 wt % of the waste coffee grounds, a modified polypropylene, an inorganic filler, and a thermoplastic elastomer.

Silylation of Copolymers Comprising Para-Methylstyrene: Synthesis and Composites Thereof

A composition, including: a copolymer including units derived from ethylene, one or more α-olefins, one or more substituted styrene compounds, and a pendant alkoxy silane group. A method was disclosed to incorporate pendant alkoxy silyl groups onto the benzylic positions. The silane-functionalized polymers show ability to cure with water. Additionally, blends of silane-functionalized polymers exhibit improved filler acceptance.

Vulcanized Polymer Blends

A heterogeneous vulcanized polymer blend comprising a continuous phase comprising a thermoplastic polypropylene having a crystallinity of at least 30% and a dispersed phase comprising particles of an elastomeric copolymer dispersed in the continuous phase and having an average particle size of less than 5 micron.
