Disclosure of Invention
Problems to be solved by the invention
The cyclic olefin polymer is liable to generate microcracks after a high temperature and high humidity test, and the generated microcracks reduce the optical properties of the molded article. That is, the internal haze of the molded article increases due to microcracks, and the optical characteristics as lenses, for example, decrease.
As one of the methods for preventing the generation of microcracks, there is a method of adding a hydrophilic stabilizer to a cyclic olefin polymer. By adding the hydrophilic stabilizer, the generation of microcracks can be prevented.
However, according to the studies of the present inventors, it is known that: depending on the kind of the hydrophilic stabilizer, dirt derived from the hydrophilic stabilizer may adhere to a portion of the mold that contacts the molded article and a portion of the mold vent during molding. If dirt adheres to the portion of the mold that contacts the molded article, the dirt adheres to the surface of the molded article. For example, when a lens is molded, dirt adheres to the lens surface, and the optical characteristics are degraded.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a cycloolefin resin composition capable of suppressing the generation of microcracks and the generation of mold contamination.
Means for solving the problems
The present inventors have made intensive studies to solve the above problems. The result shows that: the present invention has been completed by solving both the generation of microcracks and the mold contamination by using a specific hydrophilic stabilizer and a monoester of glycerin or diglycerin with a fatty acid having a molecular weight lower than that of the above hydrophilic stabilizer.

The cycloolefin resin composition according to the present embodiment can be preferably formed into a molded body. The method for molding the cycloolefin resin composition to obtain the molded article is not particularly limited, and a known method can be used. Depending on the use and shape thereof, for example, extrusion molding, injection molding, inflation molding, blow molding, extrusion blow molding, injection blow molding, compression molding, vacuum molding, powder slush molding, calendaring molding, foaming molding, and the like can be applied. Among them, the injection molding method is preferable from the viewpoints of moldability and productivity. The molding conditions are appropriately selected depending on the purpose of use or the molding method, and the resin temperature at the time of injection molding is usually in the range of 150 to 400 ℃, preferably 200 to 350 ℃, more preferably 230 to 330 ℃.
The cycloolefin resin composition according to the present embodiment can be obtained, for example, by the following method: a method of melt-kneading the cyclic olefin polymer (a) and other components added as needed by using a known kneading apparatus such as an extruder or a banbury mixer; a method in which the cyclic olefin polymer (A) and other components added as needed are dissolved in a common solvent, and then the solvent is evaporated; and a method in which a solution of the cyclic olefin polymer (A) and other components added as needed is added to a poor solvent to precipitate the polymer. The diester compound (B) and the monoester compound (C) may be added before or during kneading when they are melt-kneaded in a kneading apparatus such as an extruder or a banbury mixer.
Next, the obtained molded article is annealed at a temperature ranging from (the glass transition temperature (Tg) of the cyclic olefin polymer (A) to 40) DEG C to (the glass transition temperature (Tg) of the cyclic olefin polymer (A) to 5) DEG C for 2 to 8 hours, for example, to obtain an optical member. By performing the annealing treatment, molecules of the cyclic olefin polymer (a) in the molded article relax, and the free volume decreases. Therefore, even when the heat treatment is performed, a change in specific gravity (change in volume) is less likely to occur.
Here, if the annealing treatment is performed under severe conditions, the molded article is deformed and cannot be recovered, and therefore, it is preferable to perform the annealing treatment under the above conditions within a range where the molded article is not deformed. That is, the annealing treatment is preferably performed at a temperature and for a time period such that deformation of the molded article is not caused.
The optical member obtained as described above was excellent in wet heat resistance. Therefore, the increase in internal haze before and after the wet heat resistance test can be suppressed, and the composition can be suitably used mainly for optical applications and lenses. In addition, since transparency can be maintained before and after the wet heat resistance test, the film can be suitably used for applications requiring transparency.
While the embodiments of the present invention have been described above, these are examples of the present invention, and various configurations other than the above can be adopted.
The present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within a range that can achieve the object of the present invention are also included in the present invention.

(extrusion)
After the molten resin a was charged from the resin charging section of the extruder using a twin-screw kneading extruder with a vent, for the purpose of removing volatiles, the molten resin a was sucked from the vent section via a cold hydrazine (trap) by a vacuum pump, and 0.70 parts by mass of a triglycerin fatty acid ester compound (B-1) (wherein the amount of the triglycerin fatty acid diester compound (B) was 0.28 parts by mass) relative to 100 parts by mass of the resin a and 0.50 parts by mass of a glycerin fatty acid ester compound (C-1) (wherein the amount of the glycerin fatty acid monoester compound (C) was 0.495 parts by mass) were added to the barrel section on the downstream side of the vent section, and kneaded on the downstream side of the extruder. At this time, the conditions of the extruder were adjusted so that the difference between the maximum value and the minimum value of the resin temperature of the extruder splitter portion was 3℃or less.
Then, the kneaded product was pelletized by a water immersion pelletizer (underwater pelletizer) attached to the outlet of the extruder, and the obtained pellets were dried with hot air at 100℃for 4 hours.
Further, a resin of about 3 to 5 times the amount of the resin calculated from the average residence time in the polymerizer was flowed into the polymerizer to be washed, and then a sample was collected to obtain a resin composition containing a resin A. In order to suppress the mixing of iron atoms (Fe), stainless steel piping and polymerizers are used in polymer production equipment.
