    摘要： Provided is a process for producing an aqueous dispersion liquid, wherein, in an aqueous medium, an ethylene/(meth)acrylic acid copolymer (A) containing (meth)acrylic acid-derived constituent units in an amount of 8% by mass or more is neutralized by using an alkanolamine (B) and dispersed. The above-described alkanolamine (B) is preferably represented by general formula (1) below.

    [In general formula (1) above, R 1 to R 3 represent independently of each other a hydrogen atom, an alkyl group, or a saturated aliphatic hydrocarbon group having one hydroxyl group, and at least one of R 1 to R 3 represents a saturated aliphatic hydrocarbon group having one hydroxyl group.]

    摘要： Provided is a method for increasing the melt flow of a composition comprising a mixture of high molecular weight carboxylate functionalized ethylene copolymers (Mw between 80,000 and 500,000 Da) with low molecular weight carboxylate functionalized ethylene copolymers (Mw between 2,000 and 30,000 Da), wherein the carboxylic acid groups are at least partially neutralized to form salts containing zinc cations. The method comprises melt mixing the composition with ionomers containing cations other than zinc. Also disclosed are trimodal compositions comprising high molecular weight terpolymers, high molecular weight dipolymers and low molecular weight dipolymers wherein the carboxylic acid groups are at least partially neutralized to salts containing zinc cations and non-zinc cations. The compositions are used in films, multilayer structures and other articles of manufacture.
