摘要
The annular olefin opening ring copolymer of this invention has the structural unit of specification, the differential differential scan heat quantity curved line of DSC shows single peak, at the same time startup temperature width of the said peak is below the 35C, glass transition temperature (Tg) it features that it is above the 110C. According to this invention, it is superior, ideally be able to form the film and the seat, at the same time, near Tg relatively low temperature being, it is possible in heat resistance and optical quality without causing the trouble of the white and the like to offer the annular olefin copolymer which stretching can thing it does. In addition, according to this invention, this kind of annular olefin copolymer is included, it is superior in optical quality, and heat resistance relatively ideal, it is possible the fact that the film or the seat is offered to also stretching in low temperature. Furthermore, according to this invention, it is superior in optical quality, and heat resistance the phase difference board and which possesses uniform phase difference it is produced to offer its production method.
