“…As reported, CPE has been applied to toughen many different polymers, such as HDPE, 8 PVC, [9][10][11][12] and PMMA. 13 Furthermore, the mechanical properties, rheological properties, morphology, and thermomechanical degradation of CPE/SAN, [14][15][16] CPE/ASA, 17 CPE/PVC/ SAN, 18 and PVC/SAN 19 blends were investigated in the literature, which found a good compatibility and a high toughening efficiency.…”

The effect of chlorinated polyethylene (CPE) on the impact toughness of acrylonitrile-styrene-acrylic (ASA) terpolymer/ styrene-acrylonitrile copolymer (SAN) binary blends (25/75, w/w) was systematically investigated at three different temperatures (230 8C, 0 8C, and 23 8C). With the addition of 60 phr CPE, the impact strength increased by 11 times at 23 8C and 10 times at 0 8C. However, the toughening effect was not obvious when the testing temperature was 230 8C. Since the glass-transition temperature (T g ) of CPE was about 218.3 8C as measured with dynamic mechanical analysis tests, the polymeric chains of CPE have been "frozen out" at 230 8C. As a result, CPE evidently cannot improve the toughness of the blend system. The morphology of impactfractured surfaces observed by scanning electron microscopy also confirmed the effect of CPE on the impact toughness of ASA/SAN binary blends. The heat distortion temperature remained almost unchanged, indicating that the improvement in toughness did not sacrifice heat resistance. Furthermore, other mechanical properties were evaluated, and the possible interactions among components of the blends were also analyzed by Fourier transform infrared spectra.

“…Otherwise, the high toughening effect in PVC/CPE is between 10 and 25 phr. Du 7 prepared CPE chlorinating‐graft hydroxy ethyl acrylate copolymer (CPE‐ cg ‐HEA) and used it to toughen PVC. Compared with normal CPE, CPE‐ cg ‐HEA have better improvement on tensile property and impact strength.…”

In this work, different toughening agents such as chlorinated polyethylene (CPE), acrylonitrile–styrene‐acrylate (ASA) terpolymer, acrylic modifier (ACR, the main component is poly(methyl methacrylate‐butyl acrylate)) and polycarbonate‐polydimethylsiloxane block copolymer (PC‐b‐PDMS) were used to toughen polyvinyl chloride (PVC). Different content toughening agents (10 and 20 phr) were added into PVC and their properties were tested. The results exhibited that ACR, ASA, and PC‐b‐PDMS‐40 (40% PDMS content) had high impact strength (more than 100 kJ m−2) at room temperature. With the decrease of temperature, the toughening effect of ACR and ASA dropped significantly (7.30 and 3.69 kJ m−2 at −30°C respectively), while PC‐b‐PDMS‐40 still had certain toughening effect (19.66 kJ m−2 at −30°C). The tensile and flexural strength of blends decreased with the addition of toughening agents, while due to strong interactions between PC and PVC, elongation at break of PVC/PC‐b‐PDMS also have obvious drop. Heat distortion temperature results showed that the heat resistance of PVC was not reduced by toughening agents except CPE. The DMTA curves of blends revealed the reason why PVC/PC‐b‐PDMS‐40 had good toughness at low temperature that the glass transition temperature of PDMS is very low (−123°C), which makes it flexible at low temperature.

“…However, at least 10% (by mass) of CPE is needed to form a network structure and thus provide a good improvement in toughness. 14,16 However, a high loading of CPE will also inevitably reduce the strength and modulus of PVC products. A great deal of related work has been done to solve this problem.…”
