Patent ID: 7410695

Claim:
A thermoplastic resin composition comprising at least 80% of a reaction product resulting from the melt mixing of; A) a nylon thermoplastic resin, and B) a siloxane modified amide having the formula; where, (1) DP (degree of polymerization) is 1-700, (2) n is 1-500, (3) X is a linear or branched chain alkylene having 1-30 carbons, (4) Y is a linear or branched chain alkylene having 1-40 carbons, wherein, (a) the alkylene group may optionally and additionally contain in the alkylene portion at least one of (i) 1-3 amide linkages; (ii) a C5 or C6 cycloalkane; or (iii) phenylene, optionally substituted by 1-3 members which are independently C1-C3 alkyls; (b) the alkylene group itself may optionally be substituted by at least one of (i) hydroxy; (ii) a C3-C8 cycloalkane; (iii) 1-3 members which are independently C1-C3 alkyls; phenyl, optionally substituted by 1-3 members which are independently C1-C3 alkyls; (iv) a C1-C3 alkyl hydroxy; or (v) a C1-C6 alkyl amine; (c) Y can be Z where Z is T(R 20 )(R 21 )(R 22 ) where R 20 , R 21 and R 22 are each independently linear or branched C1-C10 alkylenes; and T is CR in which R is hydrogen, the group defined for R 1 -R 4 , or a trivalent atom such as N, P and Al; (5) each of R 1 -R 4 is independently methyl, ethyl, propyl, isopropyl, a siloxane chain, or phenyl, wherein the phenyl may optionally be substituted by 1-3 members, which are methyl or ethyl; and (6) X, Y, DP, and R 1 -R 4 may be the same or different for each polyamide unit.
