Annotation:
Petroleum resources are extensively used for the production of plastics, which are typically stable in the environment for a long time and in many application fields this could be a disadvantage. This could be avoided by using bioplastics. Glycerol, as a by-product of biodiesel production, or glycerol derivatives can be used as starting materials for the preparation of biodegradable plastics. Photocross-linked polymers and polymer composites of glycerol diglycidyl ether were obtained under ultraviolet/visible light. The suitability of the composition of glycerol diglycidyl ether and 3′,4′-epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate for the formation of 3D structures by optical 3D printing was confirmed by photolithography, dynamic projection lithography, and 3D laser lithography experiments. After evaluating the mechanical properties, the photocross-linked polymer composites of glycerol diglycidyl ether and biobased industrial waste materials (rapeseed cake, phosphogypsum, and horn meal) could be used as potential mulching coatings.
