Problems solved by technology

However, if figure 1 As shown in the schematic diagram, the molecular structure of the polar group-containing olefin copolymer produced by the high-pressure radical polymerization method is a multi-branched molecular structure irregularly having multiple long-chain branches and short-chain branches, and there are differences in strength. full of shortcomings
[0006] On the other hand, although polymerization methods by using catalysts have been explored in the past, such as figure 2 The schematic diagram of the method for producing a polar group-containing olefin copolymer with a linear molecular structure, but the polar group-containing monomer is generally a catalyst poison, so polymerization is difficult. In fact, it has been believed for many years that the Industrially inexpensive and stable methods to obtain polar group-containing olefin copolymers with desired physical properties are difficult

[0137] (Preparation of the sample)

[0138] For samples, a solution of 1 mg / ml solution was prepared using ODCB (2,6-di-tert-butyl-4-methylphenol)), and dissolved at 140 ° C for about 1 hour.

[0139] (Calculation of molecular weight (m))

[0140] The standard polystyrene method is carried out, and the maintenance capacity to the molecular weight is performed using a pre-made calibration curve based on standard polystyrene. The standard polystyrene used is the product name F380, F288, F128, F80, F40, F20, F10, F4, F1, F40, F20, F10, F4, F1, A5000, A2500, A1000 of Dongcao, Saganda Electric Company, USA (S-7300, S-3900, S-1950, S-1460, S-1010, S-565, S-152, S-66.0, S-28.5, S-5.05 each 0.07 mg / ml solution), and the like. The injected standard polystyrene is injected into 0.5 mg / ml to dissolve 0.2 mL of ODCB (containing 0.5 mg / mlbht) to produce a calibration curve. The calibration curve uses the result of approximation using a three-step approximately four-multipline approxima...

Abstract

This composition is characterized by comprising: (X1) 100-60% by weight of an ionomer characterized in that, in a copolymer (P) that includes as essential constituent units a structural unit (A) derived from ethylene and / or an alpha-olefin with a carbon number from 3 to 20 and a structural unit (B) derived from a monomer with a carboxyl group and / or a dicarboxylic acid anhydride group, at least a portion of the carboxyl group and / or the dicarboxylic acid anhydride group is converted into a metal-containing carboxylate that contains metal ions of at least one type chosen from group 1, group 2, or group 12 on the periodic table and, when the absolute value G* of the complex elastic modulus, measured with a rotational rheometer, is 0.1 MPa, the phase angle delta is 50-75 degree; and (X2) 40-0% by weight of an ethylene-based copolymer having ethylene produced by high-pressure radical polymerization as an essential monomer.

Description

Technical field [0001] The present invention relates to a laminated polymer composition using a new type of ionomer and a laminate using it. Background technique [0002] In the past, as a substrate for packaging, a polyamide resin having excellent mechanical strength, polymethylene terephthalate resin, polypropylene resin, or the like. However, these resins have high heat sealing temperatures, and cannot improve the packaging speed, and the film shrinkage in the heat seal thus the packaging appearance is deteriorated, and the heat sealing strength is low. Therefore, these substrates are randomly used alone, typically used as a composite film obtained by using the substrate as a laminated substrate, which is placed on which a laminated polyethylene resin or the like is provided. For example, the liquid package is known to provide a composite film of the sealing layer on the surface substrate layer, or a package film obtained by laminating various intermediate layers on the substr...
