| titleOfInvention | PROCESS FOR THE PREPARATION OF A TRANSPARENT MATERIAL OF THE THERMOSETTING POLYMER / THERMOPLASTIC POLYMER ALLOY TYPE AND ITS APPLICATION IN THE OPTICS FOR THE MANUFACTURE OF ORGANIC GLASSES. |
| abstract | The present invention relates to a process for preparing a transparent molded article comprising an alloy of a thermoset polymeric material forming the matrix of said article, and a thermoplastic polymer material dispersed within said thermoset polymeric material, said method comprising at least the following steps: i) preparing a liquid polymerizable mixture by dissolving said thermoplastic polymer material in a precursor thermosetting composition of said matrix, ii) filling a mold with the liquid polymerizable mixture prepared in step i), iii) polymerizing the liquid polymerizable mixture until a hardened polymer alloy is obtained; and demolding the molded article formed by said polymer alloy, said method being characterized in that the thermosetting composition comprises at least 60% by weight of 4,4'-di (ethoxyethyl) bisphenol dimethacrylate and at least 12% by weight ids of at least one monofunctional or multifunctional acrylic comonomer, and in that the thermoplastic polymer material comprises at least one triblock polystyrene-block-polybutadiene-block-poly (methyl methacrylate) copolymer (PS-b-PB-b- PMMA). The invention also relates to a transparent molded article obtained by this method as well as the polymerizable liquid mixture prepared in step i). |
