DETAILED DESCRIPTION OF THE INVENTION The present invention relates to transparent polyamide resin compositions with improved flexibility. Transparent polyamide is used for shower handles, oil filters, various covers, housings, eyeglass frames, etc. because of its chemical resistance, heat resistance, impact resistance, and cold resistance. Among these, it is particularly suitable for use in frames. 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, when the lenses are attached,
This may cause problems such as the lens not fitting in or the frame and lens being damaged. For this reason, it is necessary to change the elastic modulus of the resin used depending on the shape, thickness, etc. of the frame to make it flexible. To solve this problem, manufacturers are trying to change the rigidity or elastic modulus by changing the polymer composition. However, when improving the physical properties by going against the polymerization process, it is difficult to respond precisely to the needs of users, and an increase in grades increases costs, making it uneconomical. As a result of intensive studies to solve the above problems, the present inventors have found that by blending nylon 12 copolymer with transparent polyamide and molding it, a transparent material with improved flexibility without sacrificing transparency was created. It became possible to supply polyamide. That is, the present invention involves blending 5 to 200 parts by weight of a copolyamide containing a nylon 12 monomer as an essential component with 100 parts by weight of a transparent polyamide containing lauryl lactam and bis(4-aminocyclohexyl)methane as an essential monomer component. characterized by
The present invention relates to a transparent polyamide resin composition which can obtain any flexibility without impairing transparency and is inexpensive. The transparent polyamide referred to in the present invention is obtained by copolymerizing lauryllactam and bis(4-aminocyclohexyl)methane as essential monomer components and further monomers such as isophthalic acid, terephthalic acid, and isophorone diamine. It is a polyamide resin that has a cyclic compound in its molecule and has excellent rigidity, heat resistance, and transparency. Specifically, Japanese Patent Application Publication No. 1983
-45924 etc. can be used. In the present invention, the copolyamide containing nylon 12 monomer as an essential component is 12-aminododecanoic acid lauryl lactam, nylon 6, nylon
66, nylon 610, nylon 612, etc.
A polyamide resin obtained by copolymerizing one or more species. The above-mentioned copolyamide has a small elastic modulus, unlike transparent polyamide. 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 the amount is too low, 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 restrictions on the method of kneading and blending the copolymerized polyamide with the transparent polyamide, and any known blending method may be employed, but the dry blended resin may also be injection molded as it is. The compositions according to the invention may further contain customary additives such as oxidation stabilizers, flame retardants, UV stabilizers, heat stabilizers or pigments. Next, the present invention will be explained using examples. Example 1 Nylon 6 was added to 100 parts by weight of a transparent polyamide obtained by copolymerizing 35 parts by weight of lauryl lactam, 19 parts by weight of bis(4-aminocyclohexyl)methane, 15 parts by weight of isophoronediamine, and 30 parts by weight of isophthalic acid.
- 25 parts by weight of nylon 12 copolymer (copolymerization ratio 20/80) was kneaded, molded into a 1/2″ x 1/8″ x 5″ bending test piece, and the transparency and flexural modulus were measured. Example 2 50 parts by weight of the copolyamide in Example 1 was blended with 100 parts by weight of the transparent polyamide in Example 1, and the same test as in Example 1 was conducted. Example 3 The transparent polyamide in Example 1 100 parts by weight of the copolyamide in Example 1 was blended with 100 parts by weight of the polyamide, and the same test as in Example 1 was conducted. 200 parts by weight of polyamide was blended. Comparative Example 1 The same test as in Example 1 was conducted using only the transparent polyamide in Example 1. Comparative Example 2 Butylbenzene, a plasticizer for nylon, was added to 100 parts by weight of the transparent polyamide in Example 1. 20 parts by weight of sulfonamide was blended. The above results are shown in Table 1. Example 5 100 parts by weight of the transparent polyamide in Example 1 was mixed with nylon 12-nylon 6-nylon 66 copolymer (monomer ratio 1:1:1). ) is blended with 100 parts by weight,
Transparency and flexural modulus were measured in the same manner as in Example 1. Good transparency and flexural modulus of 18500Kg/
