  • EPOXIDIZED FATTY ACID ALKYL ESTER PLASTICIZERS AND METHODS FOR MAKING EPOXIDIZED FATTY ACID ALKYL ESTER PLASTICIZERS
    Publication number: 20150337112
    Abstract: Epoxidized fatty acid alkyl esters and methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing fatty acid alkyl esters with an acid and a peroxide. Epoxidation can be performed under controlled reaction conditions to provide epoxidized fatty acid alkyl esters having an iodine value in the range of from 4 to 15 g I2/100 g of epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizer compositions, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.

  • METHODS FOR MAKING EPOXIDIZED FATTY ACID ALKYL ESTERS
    Publication number: 20150252014
    Abstract: Methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing a natural oil with an acid and a peroxide. Residual acid in the epoxidized natural oil is not neutralized, such as with a base, prior to esterification to produce the epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizers, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.
