The recycled poly(vinyl chloride) (r-PVC) collected from the data cable has been incorporated into the recycled poly(methyl methacrylate) (r-PMMA) matrix in different weight percentage through the melt blending technique. The obtained recycled blends were analysed for mechanical, rheological, thermal and morphological characteristics. Among the various recycled blends formulated, 70:30 wt% of r-PVC/r-PMMA exhibits higher fracture toughness value. The rheological analysis highlights that recycled blends have pseudo-plastic characteristics. Furthermore, the storage and loss modulus values are decreasing with the increment of r-PVC in the recycled blend. The scanning electron microscope (SEM) study reveals the transformation of recycled blend matrix from brittle to the ductile character with the higher concentrations of r-PVC. Similarly, the water absorption, chemical resistance behaviour of the developed blends was depended on the concentration of r-PVC in the recycled blend.

从数据电缆收集的回收聚氯乙烯（r-PVC）已通过熔融共混技术以不同的重量百分比掺入回收的聚甲基丙烯酸甲酯（r-PMMA）基质中。分析所得的回收共混物的机械，流变，热和形态特征。在配制的各种再生混合物中，r-PVC / r-PMMA的70:30 wt％表现出更高的断裂韧性值。流变学分析表明，回收的共混物具有假塑性特征。此外，随着再生共混物中r-PVC的增加，储能模量和损耗模量值逐渐降低。扫描电子显微镜（SEM）研究表明，随着r-PVC浓度的增加，回收的共混物基质从脆性转变为韧性。同样，
