Zusammenfassung: | A thermoset material containing β-hydroxy esters wherein said thermoset material is subject to a mechano-chemical process to regenerate an epoxide and a carboxylic acid functionality. A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce porosity-free castable resins and vulcanize rubber formulations based on epoxidized natural rubber. Materials made from disclosed materials may be advantageously used as leather substitutes.
Un material termoestable que contiene ß-hidroxiésteres en el que dicho material termoestable está sometido a un proceso mecanoquímico para regenerar un epóxido y una funcionalidad de ácido carboxílico. Se crea un curativo para aceites epoxidados de origen vegetal y caucho natural epoxidado a partir de la reacción entre un ácido polifuncional de origen natural y un aceite epoxidado a base de plantas. El curativo se puede utilizar para producir resinas fundibles sin porosidad y vulcanizar formulaciones de caucho basadas en caucho natural epoxidado. Los materiales hechos a partir de materiales descritos pueden ser utilizados ventajosamente como sustitutos del cuero. |
