Abstract Conducting polymers are finding new application areas in energy storage devices, optoelectronics, actuators etc. Iodine doped semiconducting prevulcanized natural rubber latex (RVNRL) is a potential candidate for many such applications. We had already demonstrated for the first time that pre-vulcanized NR latex can be doped by iodine to become electrically conducting and doping process is not affecting the flexibility or processability of the films. Synthesis and characterization of intrinsically electric conducting preculcanized natural rubber latex are briefly discussed. Further, dynamical mechanical properties of these doped RVNRL are reported. The glass transition (Tg) temperature of the chemically doped polyisoprene material was found to be shifted to higher temperature region with the iodine concentration. However, the mechanical properties are found to decrease at higher concentration of the dopant after showing an increasing trend as in the case of Tg at lower doping levels. An effort has also been made to explain this visibly contradictory behavior.

Abstract In this work, an environmentally friendly type plasticizer was introduced. The synthesis consisted of two steps. In the first step, castor oil (CO) was acrylated and then the acrylated castor oil (ACO) was epoxidized with the presence of formic acid and hydrogen peroxide in the second step. The epoxidized acrylated castor oil (EACO) was characterized by FTIR and 1H-NMR techniques. The EACO was used as a main plasticizer to obtain plasticized PVC materials and compared with DOP. The results showed that EACO improved polyvinyl-chloride (PVC) plasticization performance and reduced Tg from 81.06°C to 1.40°C. Plasticized PVC materials with EACO showed similar mechanical properties and better thermal stability than DOP. EACO had better volatility stabilities, migration and solvent extraction in PVC than DOP. EACO can be used to replace DOP to prepare soft films.
