  • Patent number: 9388292
    Abstract: 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.
    Type: Grant
    Filed: March 24, 2014
    Date of Patent: July 12, 2016

  • Publication number: 20090149586
    Abstract: The present descriptive report refers to a patent of invention of primary PVC plasticizers composed of epoxidized ethyl and/or isoamyl esters of vegetable oil fatty acids and to the compounds of PVC plasticized with epoxidized bioesters, belonging to the technical field of polymer additives, developed from renewable sources such as vegetable oils and sugar cane, to reduce the cost and improve the properties of PVC compounds. The epoxidized bioesters are suitable to be added to at least one PVC resin and are obtained from a transesterification reaction of at least one type of vegetable oil with ethanol or isoamylic alcohol and subsequent epoxidation, presenting oxirane index equal to or less than 8.
