- the content of alkyl acrylate in the gel was quantitatively measured through 1 HNMR analysis or FT-IR analysis.
- the gel content is obtained by adding 1 g of the pellets extruded from the thermoplastic resin composition to 30 ml of acetone, followed by stirring at 210 rpm for 12 hours with a stirrer (Orbital Shaker, equipment name: Lab companion SKC-6075) at room temperature for 12 hours and centrifuging it ( Insoluble fraction not dissolved in acetone was collected by centrifugation at 0 °C at 18,000 rpm for 3 hours using Supra R30 of Hanil Science Co., Ltd. After drying in a forced circulation drying method for a period of time, the weight was measured and calculated by Equation 2 below.
- Graft rate (%) [weight of grafted monomer (g) / rubber weight (g)] * 100
- MI Flow index
- Elongation (%) Elongation was measured with an injection specimen (thickness 3.2 mm) under a cross head speed of 50 mm/min according to ASTM D638.
- Rockwell hardness was measured with an R-scale in accordance with ASTM D785 with an injection specimen (thickness 3.2 mm).
