Weathering properties and hydrolysis of poly(butylene terephthalate)/poly(acrylonitrile‐co‐styrene‐co‐acrylate) blend with reactive compatibilizer

Abstract

The effects of compatibilizer on the weathering properties and hydrolysis of the poly(butylene terephthalate) (PBT)/poly(acrylonitrile‐styrene‐acrylate) (PolyASA) blend (70/30 wt %) were investigated. Poly(ethylene‐co‐glycidylmethacrylate‐g‐styrene‐co‐acrylonitrile) (EGMA‐g‐SAN) was used as a compatibilizer of the blend. When the EGMA‐g‐SAN content was 3 phr, the impact and tensile strengths of the PBT/PolyASA blend showed maximum; as the EGMA‐g‐SAN content was increased from 0 to 3 phr, the impact strength of the blend increased from 6.1 to 9.5 kJ m−2. The rheological results showed that when the EGMA‐g‐SAN was 3 phr, the storage modulus and complex viscosity of the blend also showed maximum value. The mechanical and rheological results of the blend were consistent with the morphological result that when the EGMA‐g‐SAN was 3 phr, PolyASA domain size of the blend showed minimum. The weathering results showed that when the EGMA‐g‐SAN content was 3 phr, the gloss value of weathered surface of the blend showed maximum. After hydrolysis test, when the EGMA‐g‐SAN content was 3 phr, the impact and tensile strengths of the blend showed maximum. The mechanical, rheological, and weathering results suggested that EGMA‐g‐SAN is an effective compatibilizer in the PBT/PolyASA blend, and the optimum compatibilizer content is 3 phr. © 2018 Wiley Periodicals, Inc.

Ocean plastics: environmental implications and potential routes for mitigation – a perspective

“…To combat the effects of degradation, research has often combined compatibilizing agents with plastics to repair molecular chains and improve performances. 9 Such strategies are being implemented with recycled ocean plastics and will likely continue if the goal is to upcycle oceanic plastics. As a result, upcycled ocean plastics come at a price premium and are of lower quality to virgin plastics.…”

Effects of hybrid fillers on the electrical conductivity, EMI shielding effectiveness, and flame retardancy of PBT and PolyASA composites with carbon fiber and MWCNT

“…To improve the impact strength, PBT and PolyASA (70/30) with the CF and MWCNT composite was prepared in this study. When the higher content PolyASA is added in the composite, thermal property such as heat distortion temperature may decrease . Therefore, optimum PolyASA content was thought to be 30 wt % in the PBT/PolyASA with the CF and MWCNT composite.…”

“…When the higher content PolyASA is added in the composite, thermal property such as heat distortion temperature may decrease. 16 Therefore, optimum PolyASA content was thought to be 30 wt % in the PBT/PolyASA with the CF and MWCNT composite. For the PBT/PolyASA with carbon filler composite which has good flame retardancy and electrical properties, it can be used in the under the hood application of the electrical vehicle, such as battery case or connector housing.…”
