Abstract
This disclosure relates to a cross-linking polymer including polyamide-based segments having a specific structure and polyether-based segments having a specific structure, wherein the polyamide-based segments are bound to the polyether-based segments via a residue of an aromatic compound including at least one amine group and at least one carboxylic group, a polymer resin composition including the cross-linking polymer and a polyamide-based resin having relative viscosity of 2.5 to 4.0, and a polymer film including a base film layer including a melt-extrusion of the polymer resin composition.
Claims16
A cross-linking polymer comprising:
- polyamide-based segments including repeat units of the following Chemical Formula 1 or Chemical Formula 2;
- and polyether-based segments including repeat units of the following Chemical Formula 3,
- wherein the polyamide-based segment is bound to the polyether-based segment via a residue of an aromatic compound including at least one amine group and at least one carboxylic group:
- in Chemical Formula 1, R1 is a C1-C20 linear or branched alkylene group, a C6-C20 arylene group, or a C7-C20 linear or branched arylalkylene group;
- in Chemical Formula 2, R2 is a C1-C20 linear or branched alkylene group, and R3 is a C1-C20 linear or branched alkylene group, a C6-C20 arylene group, or a C7-C20 linear or branched arylalkylene group;
- and
- in Chemical Formula 3, R5 is a C1-C10 linear or branched alkylene group, n is an integer of 1 to 100, and R6 and R7 may be the same as or different from each other, and are a direct bond, —O—, —NH—, —COO—, or —CONH—, respectively.
