| titleOfInvention | Method for producing alicyclic structure-containing polymer and molded article |
| abstract | PROBLEM TO BE SOLVED: To provide an alicyclic structure-containing polymer suitable as an optical material, which can efficiently remove volatile components from a reaction solution containing the polymer, and can suppress a decrease in the molecular weight of the obtained polymer. A manufacturing method is provided. SOLUTION: A preconcentration step of removing a part of volatile components of a polymer solution containing an alicyclic structure-containing polymer to adjust the polymer concentration to 30 to 95% by weight, and a polymer concentration of 30 to 95% by weight % Of the polymer solution containing the alicyclic structure-containing polymer, and the remaining volatile components are removed to reduce the volatile component content to 1% by weight. And a drying step to be described below. According to the method of the present invention, Volatile components can be efficiently reduced, and shear stress is less likely to be applied to the resulting polymer, and polymer chain breakage is reduced. As a result, a decrease in the molecular weight of the obtained polymer can be suppressed. Moreover, a molded article molded using such a polymer has high strength, and also reduces molding defects such as coloring and silver streaks. |
