    摘要: An acrylic film with excellent flexibility is easy to process and has 70 to 95 parts by weight of an acrylic rubber-containing polymer (A) and to 30 parts by weight of an acrylic-based thermoplastic polymer (B) and having a total amount of (A) and (B) of 100 parts by weight; a gel content of 50 to 70% by weight; and elongation at break in one direction of 180% or more. The acrylic rubber-containing polymer (A) has an elastic copolymer having a monomer unit whose polymer has a glass transition temperature of more than 65° C. The acrylic-based thermoplastic polymer (B) has a glass transition temperature of 65° C. or less and a weight average molecular weight of 100,000 to 300,000.

    摘要: A heat-resisting porous membrane comprises a porous polyolefin membrane having a crosslinked copolymer held on at least a part of the pore surfaces thereof, the crosslinked copolymer being composed of a monomer (A) comprising at least one multifunctional (meth)acrylate and a monomer (B) comprising at least one monofunctional (meth)acrylate having a hydrocarbon radical of 5 to 20 carbon atoms; and the heat-resisting porous membrane can be hydrophilized by additionally having a crosslinked polymer thereon. These heat-resisting porous membranes can be used in hot water for a long period of time without deteriorating the mechanical properties inherently possessed by the matrix of the porous membrane.

    摘要: Disclosed is a hydrophobic porous membrane with a polymer having fluorinated alkyl side chains held in physical contact with the surface of a polyolefin porous membrane in which the fluorinated alkyl side chains of the polymer are crystallized, as well as its manufacturing process. Also disclosed is a hydrophobic porous membrane with a fluorinated crosslinked polymer from a fluorinated monomer with a fluorinated alkyl side chain and a crosslinking monomer held in physical contact with the surface of a polyolefin porous membrane, in which the fluorinated alkyl side chains of the fluorinated crosslinked polymer are crystallized, as well as its manufacturing process. These porous membranes use polyolefin porous membranes having a higher mechanical strength and lower costs than the fluorinated polymer porous membranes and still provide superior hydrophobicity over polytetrafluoroethylene type membranes.
