本発明は柔軟性の改善された透明ポリアミド樹脂組成Ｖ

Regarding the middle of lJ.

種カバー、ハウジング、眼鏡フレーム等に使用される。Transparent polyamide is characterized by its chemical resistance, heat resistance, impact resistance,
Because of its cold resistance, it is used for shower handles, oil filters, various covers, housings, eyeglass frames, etc.
その中でも特にフレームには好適に使用される。Among these, it is particularly suitable for use in frames.
透明ポリアミドは化学組成上、環状化合物を多く含有し

レーム及びレンズを破損する等のトラブルを生じる。Due to its chemical composition, transparent polyamide contains a large amount of cyclic compounds, has high rigidity, and has excellent impact resistance and heat resistance. However, when used in eyeglass frames, if the rigidity is too high, problems such as the lens not being inserted or damage to the frame and lens occur when the lens is attached.

。For this reason, it is necessary to make the resin flexible by changing the elastic modulus of the resin depending on the shape, thickness, etc. of the frame. To solve this problem, manufacturers are trying to change the rigidity or elastic modulus by changing the polymer composition. However, if the physical properties are improved by going against the polymerization process, it is difficult to respond precisely to the needs of users, and increasing the grade increases the cost, which is not economical.

A cyclic compound in the molecule obtained by copolymerizing 12-aminododecanoic acid or 11-aminoundecanoic acid and bis(4-aminocyclohexyl)methane as essential monomer components and further monomers such as isophthalic acid, terephthalic acid, and inphorondiamine. It is a polyamide resin with excellent rigidity, heat resistance, and transparency. Specifically, the one disclosed in Japanese Unexamined Patent Publication No. 56-45924 can be used.

することもできる。When blending copolyamide with transparent polyamide, the amount of copolyamide is 5 to 200 parts by weight, preferably 5 to 100 parts by weight, based on 100 parts by weight of the transparent polyamide, and the amount of copolyamide is 5 to 100 parts by weight. If it is too little, the softening effect will not be sufficient, and if it is more than 200 parts by weight, not only will transparency be impaired, but the original heat resistance may also be impaired. There are no particular limitations on the method of kneading and blending the copolymerized polyamide with the transparent polyamide (although any known blending method may be employed, but the triblended resin may also be injection molded as it is.
