Problems solved by technology

In addition, styrene-based resins cannot be used because they will phase-separate in most cases if a highly volatile solvent such as dichloromethane with good film-forming properties is used when forming a film. Specific Solvent Questions
Therefore, there is a problem that it takes time to dry the solvent, the productivity is extremely low, and it is difficult to easily obtain a film with high transparency.

Embodiment

[0345] Hereinafter, the present invention will be described more specifically based on examples, but the present invention is not limited to these examples. In the following examples and comparative examples, "parts" and "%" mean "parts by weight" and "% by weight" unless otherwise specified.

[0346] In the following examples and comparative examples, various measurements and evaluations were performed as follows.

[0347] [Weight average molecular weight, molecular weight distribution measurement (Mw, Mw / Mn)]

[0348] Gel permeation chromatography (GPC, product of Tosoh Corporation, trade name: HLC-8020 / four analytical columns: product of Tosoh Corporation, trade name: TSK gel G7000HxL, TSK gelGMHxL, TSK gel GMHxL, TSK gel G2000xL ), and using tetrahydrofuran (THF) as a solvent, the polystyrene-equivalent weight average molecular weight (Mw) and molecular weight distribution (Mw / Mn) were measured. The aforementioned Mn is a number average molecular weight.

Synthetic example 1

[0360] After dissolving a styrene-maleic anhydride copolymer (Dylark D232, 0.699 g) in 8.02 g of dichloroethane, 0.0438 g of aniline was added, and it stirred at room temperature for 1 hour. Resin (P1) was obtained by coagulating the reaction solution and precipitating it in methanol. The obtained IR spectrum, 1 H-NMR is shown in Figs. 1 and 2 .

[0364] The 8-methoxycarbonyl-8-methyltetracyclo[4.4.0.1 represented by the above formula (Im) 2.5 .1 7.10 50 g of ]-3-dodecene, 2.3 g of molecular weight regulator 1-hexene, and 100 g of toluene were placed in a reaction vessel replaced with nitrogen, and heated to 80°C. Add 0.09 ml of triethylaluminum (0.6 mol / L) toluene solution, methanol modified WCl 6 0.29 ml of a toluene solution (0.025 mol / L) was reacted at 80° C. for 3 hours to obtain a polymer. Then, the obtained ring-opened copolymer solution was put into an autoclave, and 100 g of toluene was further added. Relative to the amount of monomer added, adding the hydrogenation catalyst RuHCl(CO)[P(C 6 h 5 )] 3 2500ppm, the reaction was carried out for 3 hours at a hydrogen pressure of 9-10MPa and 160-165°C. After the reaction, the hydride was obtained by precipitation in a large amount of methanol solution. The obtained hydrogenated product of the ring-opened polymer (resin (P2)), its glass transition temperature (...

Abstract

A thermoplastic resin composition which is inhibited from suffering phase separation and readily gives an optical film having excellent transparency; an optical film comprising the composition as a major ingredient; a retardation film which is a film formed by stretching the optical film, shows a positive wavelength dependence, and has a low photoelastic coefficient and transparency; and a process for producing the retardation film. The thermoplastic resin composition comprises (A) a cyclic-olefin polymer and (B) a vinyl polymer having a unit represented by the following general formula (II). (II) (III) (In the formula (II), at least one of R<1> to R<4> represents a group represented by the general formula (III), and the remainder of R<1> to R<4>, if any, and R<5> and R<6> each represents hydrogen, halogeno, a (substituted) hydrocarbon group optionally having a connecting group containing a heteroatom, or a polar group, provided that R<5> and R<6> may be bonded to each other to form a monocyclic or polycyclic group optionally having a heteroatom or may in cooperation represent a divalent hydrocarbon group; and Y represents a divalent hydrocarbon group.

Description

technical field [0001] The present invention relates to a thermoplastic resin composition containing a cyclic olefin-based resin and ethylene containing a structural unit having an amide group, an optical film mainly composed of the thermoplastic resin composition, and a method for producing the same. base polymer. More specifically, it relates to an optical film having the following characteristics: good adhesion and adhesion to other materials, high transparency, and a phase imparted to transmitted light, and a method for producing the same. (In the present invention, the phase difference refers to retardation (Retardation).) The uniformity is high, and the longer the wavelength of the transmitted light, the greater the absolute value of the phase difference becomes (hereinafter, also referred to as "positive wavelength Dependency".). Background technique [0002] Conventionally, films such as polycarbonate and polyester used as optical films have a large photoelastic co...
