摘要
PVC plasticizers are composed of epoxidized bioesters of vegetable oil fatty acids obtained by partial transesterification with an alcohol, and glycerin and further acetylation and epoxidation, and PVC compounds plasticized with bioesters resulting from partial transesterification, acetylation and epoxidation, belonging to the technical field of polymer additives that were developed to improve the properties of PVC polymers, in addition to providing a lower cost for renewable compounds, such as those obtained with the use of vegetable oils. The epoxidized bioesters are composed by mixtures of epoxidized ethyl esters and acetylated and epoxidized mono, di and triglyceril esters, presenting oxirane index between 4 and 8.
