接着性樹脂組成物およびそれを用いた積層体
Document Type and Number:
Japanese Patent JP4675425
Kind Code:
B2
Abstract:
[Problem] To provide an adhesive resin having sufficient adhesion with a polar resin in any of applications at normal temperature and applications for boiling and retort processing, a resin composition comprising the adhesive resin, and further a laminate with polyolefin/polar resin including the resin composition as an intermediate layer. [Means for Solving] Provided is an adhesive resin composition (A) for a polar resin, wherein the adhesive resin composition (A) is produced by mixing a resin having a carboxylic acid anhydride or derivative thereof (a1) component with a ring-opening polymer or condensation polymer (a2) component having a hydroxyl group or an amino group at both ends or at one end; or graft-reacting the (a2) component with the (a1) component, and wherein the (a1) component is such that an acid value is from 0.1 to 50 mg KOH/g with a potassium hydroxide / ethanol solution, and the (a2) component is such that y/(x + y)*100 is 10 or more, where x is a sum of peak heights of peaks (1713 cm -1 , 1780 cm -1 ) derived from an acid anhydride group and y is a height of a peak (1740 cm -1 ) derived from an ester group, all peaks determined by infrared ray (IR) absorption spectrum measurement after melt-kneading the adhesive resin composition (A) at 220°C for 5 minutes and then cooled to room temperature.
