    1492048 Block polyetheramides SUN VENTURES Inc 14 Nov 1974 [14 Nov 1973] 49288/74 Heading C3R A block copolymer has a M.W. of 5,000 to 100,000 and comprises blocks derived from a preformed poly(dietheramide) and a preformed melt spinnable polyamide having the following repeating structural formulµ where R 1 , R 2 and R 3 are H or C 1-10 alkyl or isoalkyl; R 4 is C 1-10 alkylene or isoalkylene; R 5 is as R 4 or C 6-14 arylene; y is 2 to 100 and z is 2 to 150. It is stated that such block copolymers result from melt blending the preformed polymers at a controlled time and temperature insufficient for randomization. In specific examples poly(4,7-dioxadecamethylene) adipamide or terephthalamide is melt blended with nylon 6 under conditions ranging from 15 minutes at 282‹ C. to 360 minutes at 305‹ C.; the structure of the products is not indicated. Reference is made to Specification 562,370 which relates to a process for producing polyamides of enhanced water-absorption properties by heating in the molten state at least 2 preformed polyamides, one being water insoluble and the other water soluble until a homogeneous melt, from which not more than 10% of the soluble polyamide can be extracted is obtained but does not specify the M.W. or structure of the products. Specified water soluble polyamides are those containing oxygen in the main chain, including inter alia poly(4,7-dioxadecamethylene)adipamide, and specified insoluble polyamides include nylons 6 and 66; in most examples melt blending is at 287‹ C. for 30 minutes.

    The invention relates to a composition for the manufacture of molded articles, in particular fibers, and can be applied in the textile, spinning, automotive industry.
    The purpose of the invention is to improve the strength characteristics and moisture absorption of the molded products.
    0.2; 0.5; 1.0 and 2.0 wt.%. The mixtures are then stirred at 275 C for 30 minutes and fibers are drawn from the block copolymers obtained.
    Below are data showing the stability achieved by the introduction of an antioxidant and measured by determining the strength
    Example 1. The proposed block-10 fiber (tensile strength), isopolymer obtained by the amide exchange reaction of two source polymers, namely Nylon-6 and poly (4,7-dioxadecamethylene adipamide) (30203-6). The amide exchange reaction is carried out by melt-mixing two starting polymers at 295 ° C for 30 minutes in three different additive ratios, corresponding to 20, 25 and 30% 30203-6. In tab. 1 shows the melting points of the resulting block copolymers.
    Example 2 (prototype). The alternating polymer was obtained by copolymerizing 4j7-dioxadecamethylenediamine (30203) and caprolactam for 6 hours. The melting points of the resulting random copolymers with different concentrations of 30203 are shown in Table. one . Table 1
    From tab. 1 that alternating copolymers have lower melting points than block copolymers. This indicates that they have low strength characteristics during melt spun and stretching operations.
    Example 3. To separate samples of a dry mix of 30 weight. Poly (4.7-dioxadecamethylene adipamide) (Polymer 30203-6) and 70 weight, nylon 6 antioxidant 1, 3, 5-trimethyl-2, 4, 6-tris 3, 5-di-tert. -butyl-4-hydroxybenzylJ benzene (ethylantidoxydant 330) at concentrations of O, 1;

    0.2; 0.5; 1.0 and 2.0 wt.%. The mixtures are then stirred at 275 C for 30 minutes and fibers are drawn from the block copolymers obtained.
    Below are data showing the stability achieved by the introduction of an antioxidant and measured by determining the strength
    the tans were carried out after keeping in a drying oven for 20 minutes with forced air circulation;
