Patent ID: 7718740

Claim:
Blend containing by weight, the total weight being 100%: a) 99 to 10% of a copolymer (A) made of polyether blocks and polyamide blocks mostly constituted of repeating units resulting from the lauryllactam polycondensation, wherein said copolymer comprises 5 to 49.5 percent by weight of said polyether blocks; and b) 1 to 90% of at least a polymer (B) chosen from: 1) the polyamides that are not polyamide 12, 3) the copolymers having polyamide blocks and polyether blocks where the polyamide blocks are not mostly constituted of repeating units resulting from the lauryllactam polycondensation, wherein said blend has a higher light transmission and lower opacity than either copolymer (A) or polymer (B) alone.
