THERMOPLASTIC SATURATED NORBORNENE RESIN FILM, OPTICAL FILM AND PROTECTION FILM FOR POLARIZER

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic saturated norbornene resin film having both of high crack resistance and optical performance, an optical film and a protection film for a polarizer.

SOLUTION: The thermoplastic saturated norbornene resin film contains 5-40 pts. wt. of a rubbery polymer in 100 pts. wt. of a thermoplastic saturated norbornene resin. The disperse phase composed of the rubbery polymer is dispersed in the matrix composed of the thermoplastic saturated norbornene resin in a manner that the distance between the disperse phases becomes ≤700 nm.
