Abstract:
A nylon composition which consists essentially of a substantially uniform blend of at least one semi-crystalline copolymer I and at least one semi-crystalline copolymer II, wherein the proportion by weight of each of copolymer I and copolymer II is such that the composition has only one significant melting point; wherein(a) copolymer I is a copolymer of a semi-crystalline nylon A and a semi-crystalline different nylon B wherein nylon A is present in copolymer I in an amount of from about 70 percent to about 95 percent by weight and nylon B is present in copolymer I in an amount of from about 5 percent to about 30 percent by weight of copolymer I; and(b) copolymer II is a copolymer of semi-crystalline nylon A and at least one different semi-crystalline nylon C wherein nylon A is present in copolymer II in an amount of from about 40 percent to about 65 percent by weight and nylon C is present in copolymer II in an amount of from about 35 percent to about 60 percent by weight of copolymer II; and(c) wherein nylon A and nylon B are selected from the group consisting of nylon 6 and nylon 66; and(d) wherein nylon C is selected from the group consisting of nylon 9, nylon 11, nylon 12, nylon 46 and nylon 69.
