摘要:
Provided is a thermoplastic resin composition [X] for reduction of squeaking noises containing a rubber-reinforced vinyl resin [A] obtained by polymerizing a vinyl monomer [b1] in the presence of an ethylene -±- olefin rubber polymer [a1] having Tm (melting point) of 0°C or higher, wherein an amount of silicon contained in the thermoplastic resin composition [X] is 0.15% by mass or less based on 100% by mass of the thermoplastic resin composition[X]. According to the present invention, a structure can be provided, which is characterized in that squeaking noises that are generated when members rub against each other is remarkably reduced, that an effect of reducing squeaking noises is maintained without deterioration even when placed under high temperature for a long time, and that impact resistance and molded appearance are superior.

It is an object of the invention to provide a thermoplastic saturated norbornene resin film, an optical film, a protective film for a polarizer, a retardation film, a polarizing plate obtainable by this, which realizes the compatibility between excellent physical properties and optical characteristics, and a method of producing a thermoplastic saturated norbornene resin film. The invention relates to a thermoplastic saturated norbornene resin film, which is obtainable by using a thermoplastic saturated norbornene resin composition containing a thermoplastic saturated norbornene resin in an amount of 100 parts by weight and a rubber polymer in an amount of 5 to 40 parts by weight, parallel transmittance being 87% or more.
摘要:
Thermoplastic compositions comprise blends of 25 to 65 parts by weight of thermoplastic SAN resin and 75 to 35 parts by weight of a nitrile rubber per 100 total parts by weight of resin and rubber, in which the rubber is present as a dispersion of particles of the rubber in a matrix of the SAN resin. the rubber having a toluene-insoluble gel content of at least 85%. Preferred compositions having both thermoplastic and elastomeric properties comprise a blend of 25 to 40 parts by weight of SAN resin and 75 to 60 parts by weight of nitrile rubber. A preferred process for the production of compositions of the invention comprises continuous mastication of a blend of SAN resin and nitrile rubber with curative for the rubber at curing temperature until the required extent of cross-linking of the rubber is attained.
