Abstract

The present invention relates to a soft glycol-modified polyethylene terephthalate (PETG) resin composition and an extrusion molded article comprising the same, and more particularly, to a soft PETG resin composition, which comprises a PETG resin, a vegetable oil for reducing the hardness of the PETG resin, a TPEE (thermoplastic polyester elastomer) resin and MBS (methyl methacrylate butadiene styrene) resin for improving the physical properties of the PETG resin, and a processing aid for improving the physical properties and processability of the PETG resin, and which can be formed into an environmentally friendly film or sheet, and to an extruded article comprising the soft PETG resin composition. In a preferred embodiment, the soft glycol-modified polyethylene terephthalate (PETG) resin composition comprises 100 parts by weight of a PETG resin, 25-60 parts by weight of a vegetable oil, and 25-120 parts by weight of a thermoplastic polyester elastomer (TPEE) resin.

Description

technical field [0001] The present invention relates to a kind of soft PET-G (ethylene glycol modified polyethylene terephthalate, Glycol modified polyethylene terephthalate) resin composition and its extruded product, more specifically, to a PET-G is mixed with vegetable oil to reduce hardness, and TPEE (Thermoplastic polyester elastomer) resin and MBS (methyl methacrylate-butadiene-styrene) resin are used to ensure physical properties. Adding processing aids improves physical properties and processability, and can produce environmentally friendly films and sheets of soft PET-G resin compositions and extrusion moldings using them. Background technique [0002] Usually, plastic films or sheets are mainly made of PVC (polyvinyl chloride, Polyvinyl Chloride) or olefinic raw materials such as PP (polypropylene, Polypropylene), PE (polyethylene, Polyethylene), and avoid using them due to toxicity or environmental problems. PVC, which has weather resistance, heat resistance, adh...
