  • Patent number: 9331323
    Abstract: A cross-linkable polyolefin composition (polyethylene, polypropylene or an ethylene-propylene copolymer) is coextruded with ultrahigh molecular weight polyethylene to form two-layer separator membranes, or three-layer separator membranes, for lithium-ion battery cells. In three-layer separator membranes, the cross-linkable polyolefin is formed as the outer faces of the separator for placement against facing surfaces of cell electrodes. The polymer materials initially contain plasticizer oil, which is removed from the extruded membranes, and the extruded membranes are also stretched to obtain a suitable open pore structure in the layered membranes to provide for suitable infiltration with a liquid electrolyte. The cross-linked polyolefin layer provides strength at elevated temperatures and the lower-melting, ultrahigh molecular weight polyethylene layer provides the separator membrane with a thermal shutdown capability.

  • Patent number: 8759447
    Abstract: A compatibilizer contains a polymer (A) obtained by reacting a modified olefin-based polymer (a-1) with a polymer (a-2) containing a terminal functional group, wherein the modified olefin-based polymer (a-1) is a polymer modified with from 0.01 to 2 mass % of unsaturated carboxylic acid or a derivative thereof, and the polymer (a-2) is a ring opening polymer or condensation polymer containing a terminal functional group, capable of reacting with the modified olefin-based polymer (a-1), at both ends or one end thereof and has a number average molecular weight from 1,500 to 100,000. This provides an excellent compatibilizer. Particularly, upon melt processing a recovery of a multilayer structure including an EVOH layer and a thermoplastic resin layer, a recycling agent is provided that gives sufficient improvement effects to any of the adhesion of a degraded resin to a screw of a molding machine, the generation of die build-up, the generation of fish eyes, and the decrease in transparency.
