Definitions
- the present invention relates to a cyclic olefin resin composition and a molded article.
- Cyclic olefin polymers are used, for example, in optical lenses such as imaging lenses, f ⁇ lenses, and pickup lenses. Cyclic olefin polymers used in molded articles such as optical lenses are required to have properties such as high transparency, excellent dimensional stability, excellent heat resistance, and excellent moisture resistance. .
- Patent Document 1 describes a resin composition containing a polymer containing an alicyclic structure in at least a part of the repeating structural units, and a fatty acid ester of a fatty acid and a polyhydric alcohol having one or more ether groups.
- Patent Document 2 describes a cyclic olefin resin composition containing a cyclic olefin polymer (A) and a triglycerin fatty acid ester.
- Patent Document 3 discloses a resin composition containing an alicyclic structure-containing polymer and a polyglycerin fatty acid ester-based additive, wherein the polyglycerin fatty acid ester-based additive is one of polyglycerin fatty acid ester compounds or It consists of two or more kinds, and the content of the polyglycerol fatty acid ester additive is 0.2 to 2.0 parts by weight with respect to 100 parts by weight of the alicyclic structure-containing polymer. is described.
- Cyclic olefin polymers are prone to microcracks after high-temperature and high-humidity tests, and the microcracks that occur reduce the optical properties of molded products. That is, the microcracks increase the internal haze of the molded body, and degrade the optical properties of the lens, for example.
- One of the methods for preventing the occurrence of microcracks is to add a hydrophilic stabilizer to the cyclic olefin polymer. By adding a hydrophilic stabilizer, it is possible to prevent the occurrence of microcracks.

If dirt adheres to the part of the mold that comes into contact with the molded article, the dirt also adheres to the surface of the molded article. For example, when a lens is molded, dirt adheres to the lens surface, degrading the optical characteristics.
