Abstract
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.
