MANUFACTURING METHOD OF MOLDED OBJECTS AND OPTICAL INJECTION-MOLDED OBJECT MANUFACTURING METHOD OF MOLDED OBJECTS AND OPTICAL INJECTION-MOLDED OBJECT

摘要

The present invention relates to a manufacturing method of a molded object with a good heat resistance by using polymers with good moldability and an optical injection molded object with good heat resistance and modability wherein the manufacturing method of the molded object is allowed to mold 20-50 wt% of cyclo olefin based polymers with two type of repeated units derived from certain norbornene compounds for 100 wt% of entire repeated units like dicyclopentadiene with use of an injection mold where provided is the optical injection molded object.;COPYRIGHT KIPO 2015
