Lipase‐Catalyzed Synthesis and Properties of Poly[(12‐hydroxydodecanoate)‐co‐(12‐hydroxystearate)] Directed towards Novel Green and Sustainable Elastomers
Abstract Novel green and sustainable elastomers having both good biodegradability and chemical recyclability properties were designed and synthesized using potentially biobased materials and lipase as an environmentally benign catalyst.
