Abstract
Recycled poly(ethylene terephthalate) (rPET) from post-consumer drinking bottles was added into poly(butylene succinate) (PBS), which aimed to improve chemical resistance and also reduce cost. PBS and rPET with the weight ratios of 100/0, 90/10, 80/20, 70/30, 60/40, and 50/50 wt% were melt blended using glycidyl methacrylate (GMA) of 0, 3, and 5 phr as a compatibilizer and dicumyl peroxide (DCP) of 0.5 phr as an initiator. It was found that increasing rPET content enhanced Young’s modulus of the blends. However, tensile strength, and elongation at break of the blends were reduced due to phase separation. Incorporating GMA improved chemical compatibility resulting the PBS/rPET blends to have higher tensile strength and elongation at break. Compared to pure PBS, blending rPET improved chemical resistance to household chemicals such as bathroom cleaning liquid (hydrochloric acid based) and bleaching liquid, which the blends adding GMA showed even better chemical resistance.
