HIGHLY HEAT-RESISTANT CROSSLINKED POLYMER PARTICLES CAPABLE RESTRAINING YELLOWING AND THERMAL DECOMPOSITION IN HIGH TEMPERATURE PROCESS CONDITION, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A highly heat-resistant crosslinked polymer is provided to introduce inorganic nano particles surface-treated by a silane based compounds comprising saturated carbon, thereby capable of obtaining highly thermal resistance while maintaining excellent optical properties of polymer crosslinkable particles.;CONSTITUTION: A highly heat-resistant crosslinked polymer comprises: a step of manufacturing a monomer composition; a step of dispersing and mixing inorganic nano particles surface-treated by silane based compounds comprising unsaturated carbon, and suspension polymerizing after manufacturing suspension by adding dispersion stabilizer and ion exchanged water. The polymer crosslinkable particle has 3 weight%-loss pyrolysis initiation temperature of 300 °C or higher at thermogravimetric analysis. The monomer composition comprises one or more monomers selected from an aromatic vinyl based monomer, a C1-20 acrylate or a methacrylate alkylester monomer, and a C1-20 acrylic or methacrylic fluoroalkylester monomer, a crosslinking agent, and an initiator.;COPYRIGHT KIPO 2012
