Preparation method for a thermosetting polymer / thermoplastic polymer alloy type transparent material and its application in optics for the production of organic glasses

摘要

Process for preparing a transparent molded article comprising an alloy of a thermoset polymer material forming the matrix of the article, and a thermoplastic polymer material dispersed within the thermoset polymer material, comprises: preparing a liquid polymerizable mixture by dissolving the thermoplastic polymer material in thermosetting precursor composition of the matrix; filling a mold with the liquid polymerizable mixture; polymerizing the liquid polymerizable mixture until obtaining a hard polymer alloy; and removing the molded article formed by the combination of polymers.
