Number of biodegradable resin composition bath The butyl [leyn the car this [thu which it sees - terephthalate copolymer poly (PBCT, melt index (210 °C, 2. 16 kg) 4. 7g/10min, 104, 000g/mol weight criticism molecular weight, molecular weight distribution (Mw/Mn) 3. 53, 22N/mm2 tensile strength, break elongation 380%, 32% biodegradation also), polylactic acid (PLA, NatureWorks grade: 4032D), Joncryl® ADR-a 4368CS (chain extension number, weight average molecular weight 6, 800g/mol, epoxy equivalent weight of 215 g/eq, BASF) and hexamethylene diisocyanate (HDI, Tokyo Chemical Industry) isocyanate chain extension number include means of table 1 number the resin composition was mixed at the ratio of high pressure liquid coolant. Biodegradable resin compound from number bath Said number prepared by the biodegradable resin composition after drying in an 12 hours, torque (torque rheometer) rheometer equipped with a mixer (Brabender, Plasti-a Coder® ) Number was 7 minutes in 100 rpm using biodegradable resin compound 190 °C to blend the high pressure liquid coolant. Biodegradable resin compounding sheet number bath Real sheet compression molding the biodegradable resin compound was prepared by the number. The flat mold have 3 minutes after preheating in flow whereupon the compound 190 °C, 1 minutes 2000psi 500 by pressure with the micro m forming the thickness of his. Test example The compound prepared by the number to 30 parts by weight or sheet method melt index, tensile strength, elongation at break and biodegradable means to a predetermined position and viewing results shown table 2. [Measuring method] (1) a melt index (MI) Said number according to ASTM D1238 190 °C temperature and 2 prepared by the biodegradable resin compound. 16 kg load under 10 minutes orifice (diameter 2. 095 mm, length 9. 555 cm) were measured in an amount flowing through. (2) tensile strength and elongation Plastic films and sheets made of a tensile testing method (ASTM D8824) tensile strength and elongation were measured by using a sheet prepared by the number. 5 made of each specimen 20 provided 25 °C, 50 ± 5% relative humidity was measured under conditions. Each sample is the breadth of 20 mm, length 200 mm, distance 10 mm to by cut 200N load cell (load cell) grip (grip) equipped with UTM groups were measured. (3) also biodegradation Said number prepared by the biodegradable resin compound film made using the enzymatic resolution of a weight (- 30 micro m thickness, size - 1X1 cm2) were measured. Measuring conditions provided as follows. Biodegradable for measuring film at room temperature, under vacuum dried to liver 2 are used. Said film is subjected to enzymatic (lipase Pseudomonas sp. , Activity 35 units/mg) including a potassium phosphate buffer solution (pH 6. 86, concentration 10 units/Ml) is placed, and has between 20 degree weight swung in incubator of 37 °C were measured. When the weighing sample is washed with distilled water in an effective stand-alone minutes perfect number for a long time. The reference table 2, 4 in the embodiment 1 and comparison example 1 in the embodiment 5 according to the second com group fortune biodegradable resin prepared by the number 8 in com pound biodegradable resin prepared by the number according as compared to having low melt index, high tensile strength and elongation break into foods. In addition in the embodiment 2, 4, 6, 8 in the embodiment 1, 3, 5, 7 in com pound biodegradable resin prepared by the number according to the second com group fortune biodegradable resin prepared by the number according as compared having low melt index, high tensile strength and elongation break into foods. These results from chain extension number using compound composition by simple comparison example 1 without using a chain extension number in com pound compared to number produced therewith, the potentiating effect can be confirmed structurally high. In addition chain extension and an isocyanate-containing compound having a structure of formula 4 in compatible effect than that of a chain extension number can be effective. On the other hand, in the embodiment 1 and 2 in the embodiment 3 and 4 according to the second com group fortune biodegradable resin prepared by the number according been compared in com pound low elongation break biodegradable resin prepared by the number, the higher the flexibility polylactic acid content is reduced as in the picomolar. In addition in the embodiment 1 according to the second comparison example 1 com group fortune biodegradable resin prepared by the number 8 according to biodegradation in com pound biodegradable resin prepared by the number increased compared the advantages that a starting point, chain extension number change by observation is not biodegradable.
