More specifically, the present invention relates to a polytetramethylene adipamide (nylon 46) resin composition that exhibits excellent heat resistance, mechanical properties, low water absorption, and dimensional properties.

てその利用上の価値が大きいと考えられている。[0003] Nylon 46 resin has excellent heat resistance and excellent mechanical properties such as tensile strength and bending strength, as well as sliding properties, so it is considered to have great utility as a useful engineering plastic. .

なる。[0004] However, this nylon 46 resin has a higher proportion of amide groups than ordinary polyamide resins such as nylon 6 resin and nylon 66 resin, so it has a drawback that its water absorption rate is higher than those of them. This means that while nylon 46 resin has better heat resistance and mechanical properties than general polyamide resin in the dry state immediately after molding,
In practical use, because it has a higher water absorption rate than normal polyamide resin, it improves impact properties, but the decrease in heat resistance and mechanical properties is greater, and in some cases, the superiority of nylon 46 resin is lost. It also happens.

ている。[0005] Also, like ordinary polyamide resins, the dimensions of molded products of nylon 46 resins change due to water absorption. Nylon 46 resin has a high degree of crystallinity, so the dimensional change rate per water absorption rate is smaller than that of ordinary polyamide resin, but
The degree of dimensional change due to water absorption is not necessarily at a satisfactory level due to its high water absorption rate, and this is a major obstacle in applying nylon 46 resin to applications where its excellent properties can be utilized as engineering plastics. There is.

(See Publication No. 59-213758). Regarding nylon 46 resin, attempts have also been made to improve the properties of nylon 46 resin by combining it with polyphenylene sulfide resin, and to increase the compatibility between the two (Japanese Patent Laid-Open No. 6

くない。[0023] Polyphenylene sulfide resins crosslinked and made to have a high molecular weight by heat treatment generally have the drawbacks of poor toughness and large discoloration. This also applies when it is blended into nylon 46 resin. Further, the cross-linked high molecular weight polyphenylene sulfide resin is characterized by its high melt viscosity. This is undesirable in that it is difficult to obtain a uniformly dispersed composition when blended with nylon 46 resin, which has a low melt viscosity.

した。On the other hand, even if polyphenylene sulfide resin is not cross-linked and has a high molecular weight, if its molecular weight is too low, a composition having good toughness cannot be obtained even if it is blended into nylon 46 resin. The present inventors have found that by blending a high molecular weight polyphenylene sulfide resin that has not been subjected to crosslinking and polymerization through heat treatment into nylon 46 resin, it has good toughness, heat resistance, uniform dispersibility, less coloring, and improved water absorption characteristics. It has been found that a composition can be obtained.

The branched type can be produced by adding a small amount of a trifunctional compound such as trichlorobenzene during polymerization using the method described in Japanese Patent No. 6720 and the like. When using a trifunctional compound such as trichlorobenzene, the addition ratio of the trifunctional compound is preferably 5 mol% or less in order to maintain good fluidity of the resulting polyphenylene sulfide resin, that is, to make it substantially non-crosslinked. , more preferably 1 mol% or less.

Moreover, if the melt viscosity is 5000 poise or more, the difference in viscosity from the nylon 46 resin becomes large, making uniform dispersion difficult and making it difficult to obtain stable properties, which is not preferable.
