Problems solved by technology

Lamination of polyester film, polycarbonate film, acrylic polymer film, ethylene-vinyl acetate copolymer saponified film, polyvinylidene chloride film, polyvinyl chloride film, etc. At present, solvent-based adhesives are widely used, but there are problems in the natural environment pollution caused by the use of organic solvents, the deterioration of the working environment, and safety, and a lamination technology that does not use solvent-based adhesives is required
In addition, in resin substrates containing polar groups, since polycarbonate films, acrylic polymer films, etc. have poor solvent resistance, the solvents that can be selected are also limited.

Embodiment

[0338] Hereinafter, the present invention will be further specifically described based on examples, but the present invention is not limited to these examples.

[0339] In the following examples, various physical properties were measured and evaluated as follows. In Examples and Comparative Examples, the test methods used for various evaluations are as follows.

[0340] (1) MFR

[0341] MFR is measured according to ASTM D 1238 (230° C., load 2.16 kg). Among them, MFR 190 It is the MFR measured under the condition of temperature 190°C and load 2.16kg.

[0342] (2) Tensile test

[0343] The tensile test is based on ASTM D638, and a dumbbell-shaped test piece punched from a pressed sheet with a thickness of 1 mm is tested at 23° C., a span interval of 30 mm, and a tensile speed of 30 mm / min. However, Examples 17 to 27 were carried out at a stretching speed of 5 mm / min.

[0344] (3) Bending strength

[0345] The flexural strength was measured under the following conditions ...

[0409] Synthesis of Halogenated Polypropylene

[0410] Propylene / 10-undecen-1-alcohol copolymer (Mw=106000, Mn=56000, comonomer content 0.12 mol%) synthesized according to the method described in the embodiment of Japanese Patent Laid-Open No. 2002-145944 ) 170 g was added to a degassed nitrogen exchanged 2 L glass reactor, 1700 ml of hexane and 9.2 ml of 2-bromoisobutyryl bromide were added respectively, and heated and stirred at 60° C. for 2 hours. After the reaction, the resulting slurry was filtered and then dried under reduced pressure to obtain 169.5 g of a white solid polymer. Depend on 1 H-NMR analysis showed that 94% of the OH groups were polypropylene modified with 2-bromoisobutyric acid groups.

[0411] The number of 2-bromoisobutyrate groups per molecular chain of polypropylene calculated from the number average molecular weight of polypropylene, the comonomer content, and the modification ratio of 2-bromoisobutyrate groups was 1.5 unit.

[0413] Synthesis of Block Polymers

[0414] 100 g of the halogenated polypropylene obtained in Production Example 1 above, 786 ml of styrene (St) and 194 ml of acrylonitrile (AN) were added to a glass reactor with an internal volume of 2 L sufficiently nitrogen-exchanged, and stirred at 25°C. 246 mg of copper bromide (I) and 0.72 ml of PMDETA were added to this slurry, and superposition|polymerization was performed at 90 degreeC for 2 hours. The reaction liquid was filtered, the solid on the filter was washed with methanol, and the polymer was dried under reduced pressure to obtain 161.3 g of a solid polymer. 5.16 g of the obtained polymer was taken out, and Soxhlet extraction was performed under reflux for 9 hours using 150 ml of acetone. The extraction residue was dried under reduced pressure to obtain 5.07 g of a polymer (hereinafter referred to as block polymer (A2-1)). After extracting the sample 1 According to H-NMR analysis, the composition ratio of PP / St / AN was 63...
