Abstract:
Disclosed is a light control film, comprising: two transparent electroconductive resin substrates; and a light control layer sandwiched between the two transparent electroconductive resin substrates, the light control layer comprising: a resin matrix; and a light control suspension dispersed in the resin matrix, wherein at least one of the transparent electroconductive resin substrates has, on the light control layer side thereof, a primer layer, and the primer layer is made of a thin film comprising a material containing a urethane acrylate containing a pentaerythritol skeleton. Thus, it is possible to provide a light control film that improves the adhesion between a film matrix and a substrate, and that achieves a stable light control function.

Abstract:
Disclosed is a poly(4-methyl-1-pentene) resin composition having an excellent balance between micropore formability and toughness, which can sufficiently form fine pores by drawing and does not cause a break during drawing. The poly(4-methyl-1-pentene) resin composition contains 0-90 parts by mass of a 4-methyl-1-pentene homopolymer (A) and 10-100 parts by mass of a 4-methyl-1-pentene copolymer (B) having a structural unit derived from 4-methyl-1-pentene and a structural unit derived from a C2-20 α-olefin other than 4-methyl-1-pentene. The content of the structural unit derived from a C2-20 α-olefin other than 4-methyl-1-pentene is 0.1-2.1% by mass relative to the total amount of the homopolymer (A) and the copolymer (B). The poly(4-methyl-1-pentene) resin composition also contains 0.1-800 ppm of a nucleator (C) relative to the total weight of the homopolymer (A) and the copolymer (B).
Abstract:
The present invention provides a process for producing an α-olefin polymer comprising polymerizing or copolymerizing (a) C3 or higher a-olefin(s) in the presence of an olefin polymerization catalyst comprising solid titanium catalyst component (I) containing titanium, magnesium, halogen, and a compound with a specific structure having two or more ether linkages and organometallic catalyst component (II) with high catalytic activity. In this process, particularly even in (co)polymerizing (a) higher olefin(s), demineralization is unnecessary. A 4-methyl-1-pentene-based polymer obtained by polymerization using the catalyst of the present invention is excellent in tacticity, transparency, heat resistance, and releasability, and the polymer is particularly suitable for a release film.
