Problems solved by technology

[0010] However, it is difficult to separate from the homopolymer, so purification must be repeated many times, which becomes a high cost
Furthermore, the incorporation rate of styrenes is not stable, and there is a problem in quality, so it is not a method that can be mass-produced
In addition, the obtained block body also lacks practicality. For example, in the case of stretching operations that are often performed on optical films, there is a problem of whitening and loss of transparency.

Description

technical field [0001] The present invention relates to a block copolymer, its production method and film. More specifically, the present invention relates to a highly transparent block copolymer useful in the optical field, a method for producing the same, and a film comprising the block copolymer. Background technique [0002] Cyclic olefin-based resins such as thermoplastic norbornene-based resins have high glass transition temperature, high light transmittance, and small anisotropy of refractive index, so they have low birefringence compared with conventional optical films. specialty. Therefore, it has attracted attention as a transparent thermoplastic resin excellent in heat resistance, transparency, and optical characteristics. Further studies are being made to apply cyclic olefin-based resins to optical fields such as optical materials such as optical discs, optical lenses, optical fibers, and transparent plastic substrates, sealing materials such as optical semicon...
