Characteristic of renewable polymer incorporated with stabilizer to characterize the endurance to ultra voilet irradiation exposure

Waste vegetable from palm oils are most abundant biological sources and important raw materials for production of renewable polymer because of their versatility with high possibility to modify the chemical structure of triglycerides and it derivatives. In this study, waste vegetable oil was synthesi...
