The present study deals with some results on phase behavior, miscibility, morphology and mechanical properties for Polymethyl methacrylate and Polyvinyl chloride polymer blends prepared by solution casting method at different concentration between 0 to 100 wt %. Dynamic storage modulus (E’) and Tan δ were measured in a temperature range from 30 0C to 150 0C using DMA. The value of the storage modulus was found to increase initially but then decreased with further addition of the PVC in the matrix. Transition temperature (Tg) of pure PMMA and pure PVC is found to be at 90 0C and 52 0C, respectively. The result shows that the two polymers are miscible upto about 50wt % of PMMA. Distribution of the phases in the blends was studied through scanning electron microscopy. Also the mechanical properties like elongation at break and fracture energy of the PMMA/ PVC blends increase with the increasing concentration of PVC in PMMA indicating a high level of compatibility between the two polymers. This partial miscibility and compatibility is due to specific interaction between carbonyl groups (C= O) of PMMA and hydrogen from (CHCl) groups of PVC.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
