Description

[0001] POLYMER RESIN COMPOSITION AND MOLDED PRODUCT [0002]

The present invention relates to a polymer resin composition and a molded article using the same, and more particularly, to an environmentally friendly polymer resin composition having excellent heat resistance and appearance quality and a molded article using the same.

The polyamide (PA) resin is a linear polymeric material having repetition of an amide bond (-CO-NH-) as a main chain and is called nylon resin. PA resin is a type of engineering plastics and has excellent mechanical properties, especially chemical resistance, friction and abrasion resistance, and is widely used in general machine parts, automobile parts, electric parts and sports goods. Examples of such PA resins include nylon 6 formed by ring-opening polymerization of e-caprolactam, nylon 66 formed by ring-opening polymerization of adipic acid and hexamethylenediamine.

The PA resin is mixed with a polyester resin to improve the impact resistance and the heat resistance. However, since the PA resin and the polyester resin are not compatible with each other, the PA resin and the polyester resin are liable to be phase-separated during blending and induce an esterification reaction by melt blending or the like, Is difficult to obtain. Further, in the case of a transparent polyester, transparency deteriorates due to the inclusion of an amide component. Therefore, much research has been conducted to improve the compatibility of the PA resin and the polyester-based resin and to synthesize a copolymer that complements the physical properties of the two resins. For example, Japanese Patent Laid-Open Publication No. 51-103191 discloses a method of melt-blending polybutylene terephthalate (PBT) and nylon 6, followed by solid phase polymerization to improve the mechanical properties of the copolymer US Patent No. 5,102,935 discloses a method of forming a copolymer by inducing an ester-amide exchange reaction using p-toluenesulfone (TsOH) while melt-blending polyethylene terephthalate (PET) and nylon 66 Lt; / RTI >

However, conventional PA resins are oil-based and therefore not environmentally friendly, and generate a large amount of CO 2 when incinerated. As such, petroleum-based resins cause environmental problems such as global warming and abnormal weather, so it is required to develop environmentally friendly resin compositions that do not generate CO 2 while maintaining the merits of conventional petroleum-based resins.

Accordingly, the inventors of the present invention confirmed that a polymer resin having excellent heat resistance and appearance quality can be produced by using glass fiber (GF) and other additional resin together with the polyamide 56 resin produced from the biomass, Respectively.
