The current concern about plastic pollution has created opportunities for the production of more sustainable polymers. Inverse vulcanization, a novel procedure to obtain inorganic-organic hybrid polymeric materials, has been explored. This study formulates a new series of copolymers using castor oil and sulfur as comonomers, and adds a third compound to improve their bioactivity.
The current great concern about plastic pollution opens up opportunities for the production of more sustainable polymers. Inverse vulcanization has emerged as a novel procedure to obtain inorganic-organic hybrid polymeric materials. Sulfur is attained as a by-product of oil refining production and makes inverse vulcanization a sus-tainable process due to a large amount of sulfur without a useful life. In previous studies, vegetable oils were used as a comonomer with sulfur to form copolymers based on sustainable raw material. Nevertheless, compounds from agro-wastes, could be a third comonomer that improves new copolymers bio-applications. In this study, a new series of copolymers with castor oil as vegetable oil and sulfur was formulated by adding a third compound bearing double bonds or heteroatoms. A study was conducted to assess the antimicrobial capacity and antioxi-dant activity of the copolymers obtained to demonstrate the benefits of adding a new comonomer to improve their bioactivity.
