Latest Patents
Toyama's latest patents include a rubber-modified styrene-based resin and a light diffusion plate containing such resin. This invention discloses a rubber-modified styrene-based resin comprising a styrene-based polymer forming a matrix and rubber-like polymer particles dispersed in the matrix. The rubber-like polymer particles have a cross-sectional structure where the styrene-based polymer particles are contained like islands in a sea. The composition consists of 1-10 wt % of the rubber-like polymer and 99-90 wt % of the styrene-based polymer. The particle diameter of the rubber-like polymer particle falls within a range of 1.0 to 5.0 micrometers. Additionally, the value of the ratio of styrene-based polymer weight to rubber-like polymer weight in a methylethylketone-insoluble matter of the resin falls within a range of 0.5 to 1.5.
Another significant patent is related to a method for manufacturing a styrene-based polymer. This method involves continuously feeding raw materials into polymerization vessels connected in series. The process includes polymerizing a styrenic monomer in the presence of a (meth)acrylate ester monomer using an organic radical generating agent as an initiator. The polymerization conditions are carefully controlled to ensure optimal product quality.
