[0076] Polypropylene carbonate (PPC), polyester diol (U1420, Lianhe Chemical, MW: 2000) and polycarbonate diol ( PCDL, G3452, Asahi Kasei, MW: 2000), according to the content (parts by weight) described in the following Table 1, the resin composition having the IPN structure according to the present invention was manufactured. As a curing agent, H12MDI (4,4-dicyclohexyl-methane diisocyanate (4,4'-Dicyclohexyl-methane diisocyanate)) was used. On the other hand, Tg, Tm, test piece breaking stress (strain at break) and breaking elongation (%strain at break) were measured by UTM (Universal Test Machine), and the results are shown in Table 2.

[0082] Add polypropylene carbonate (PPC) with a weight-average molecular weight of 89,000 and an ether linkage of 0.5% or less, an epoxy compound (Kuodu Chemical YD-128) and a polyamide-based curing agent according to the content described in Table 3 below (Kunito Chemical G-640), a resin composition having an IPN structure according to the present invention was produced. On the other hand, the adhesive strength was measured by the lap shear strength (lap shear strength) using a UTM instrument. The adhered material is polycarbonate, and the test piece is based on the ASTM D 5868-01 standard, and the adhered material of 2 specified sizes (1 inch × 4 inch × 0.5mm = width × length × thickness) is divided into an area of ​​1 inch × 1 inch After stacking, the adhesive material is applied between the stacked surfaces, and the adhesive force is measured after one week. The adhesive force is measured at room temperature and 70°C. Before measuring the adhesive force, use a temperature...

[0088] Polypropylene carbonate (PPC) with a weight average molecular weight of 89,000 and an ether linkage of 0.5% or less, an acrylic compound (MMA, Oikakin) and 2,2-azobisiso as a reaction initiator were added. Butyronitrile (AIBN, Oi Kakin) and 4-methoxyphenol (4-methoxyphenol, MPh, Junsei Chemical) were used as a reaction inhibitor. The above solution is coated on the PET film with a uniform thickness of 5-7 μm at a speed of 5-100 mm / sec. The coated film was left at room temperature for 30 minutes, and then dried at 70° C. to measure the surface hardness. The surface hardness was measured with a pencil hardness tester (COAD606, Marine Science).

Abstract

The present invention relates to a polyalkylene carbonate resin composition with interpenetrating polymer networks structure. The polyalkylene carbonate resin composition with interpenetrating polymer networks structure includes an aliphatic polycarbonate formed by the reaction of one more epoxide compounds selected from an halogen or alkoxy-substituted or unsubstituted C2-10 alkylene oxide; a halogen or alkoxy substituted or unsubstituted C4-C20 cycloalkylene oxide; and a halogen, alkoxy, alkyl, or aryl-substituted or unsubstituted C8-C20 styrene oxide, an aliphatic polycarbonate and a polyol compound , an epoxy-based compound, and an acrylic compound.

Description

technical field [0001] The present invention relates to a resin composition having an interpenetrating crosslinked structure comprising an aliphatic polycarbonate obtained by copolymerizing carbon dioxide and one or more epoxy compounds. Background technique [0002] Recently, aliphatic polycarbonates are being industrialized as a method of reducing carbon dioxide generation as a measure against global warming. Aliphatic polycarbonate is a soft rubber-like plastic, has excellent processability and is easy to adjust its decomposition characteristics, and thus has been extensively studied as a biodegradable polymer. However, aliphatic polycarbonate has characteristics such as low glass transition temperature (Tg), easy decomposition around 200°C, and weak heat resistance. In addition, in terms of mechanical properties, it has characteristics such as a small elastic modulus and fragility in the case of film products, so its use in various fields is limited. In response to thi...
