“…Therefore, it is expected that ASA terpolymer can also work as an impact modifier for rigid PVC. Ren and coworkers studied the effect of AN content in SAN shell on the toughness of PVC/ASA binary blends and PVC–ASA–DOP blends. They found that the impact strength of the PVC/ASA blends and PVC–ASA–DOP blends increased and then decreased with the increasing AN content in the SAN shell.…”

In this work, acrylonitrile-styrene-acrylate (ASA) terpolymer was used to toughen rigid poly(vinyl chloride) (PVC). ASA has a core-shell structure, where the poly(butyl acrylate) (PBA) serves as the soft core while styrene-acrylonitrile (SAN) copolymer works as the rigid shell. Herein, The PBA core content in ASA was varied from 0 to 80 wt %, and its effect on the physiochemical properties was investigated. It was found that the hard shell of ASA was miscible with PVC matrix, providing good interfacial adhesion between ASA and PVC. Increasing the soft PBA content considerably improved the room-temperature impact toughness, and a sharp brittle-ductile transition (BDT) as a function of PBA content was observed. However, as the testing temperature decreased to 0 and −30 C, the toughening effect became limited, and the BDT first shifted to high PBA content region and finally disappeared. It was suggested that whether the toughening effect can be achieved depended on the thickness of hard shell and the relaxation behavior of PBA core. Albeit the loss in rigidity was accompanied, the accomplished toughening effect was not on the sacrifice of heat distortion temperature.

The lack of toughness and heat resistance of polyvinyl chloride (PVC) limit its application in construction, transportation, packaging, and medical treatment. In this work, the core–shell structure polybutadiene grafted styrene and acrylonitrile copolymer (PB‐g‐SAN), named (ABS), was utilized to toughen PVC. The composite materials reached the brittle‐ductile transition point at 10 phr. The heat‐resistant modifier styrene‐N‐phenylmaleimide‐acrylonitrile terpolymer (SMIA) synthesized by bulk polymerization was added to PVC/ABS to improve the heat resistance of the composite. The monomer N‐phenylmaleimide with a large spatial site resistance is introduced into SMIA, which restricts the molecular chain movement. There are intermolecular forces between the nitrile group and PVC to enhance the composite compatibility. Phase separation was not observed in the scanning electron microscope images of composites, elucidating the outstanding compatibility of ABS, PVC, and SMIA. The brittle‐ductile transition point was found to be 1350.60 J/m addition of 10 phr ABS. The Vicat softening temperature of the ternary functional composite (PVC/ABS/SMIA, 72:8:20) raised by 2°C, and the initial decomposition temperature increased by 19°C. Furthermore, the impact strength elevated 6 times compared to that of PVC. The toughening and strengthening heat resistance of PVC are realized at the same time.
