Disclosed is an apparatus for formation of high quality plastic sheet in a continuous fashion. Also disclosed are a variety of optical and electronic display applications for high quality plastic sheet produced in a continuous fashion.

Process and apparatus for forming plastic sheet

Disclosed is the use of certain polyglutarimides as plastic substrates for use in electronic display applications. These substrates have relatively high Tgs for plastics, and good optical clarity and flatness, with low shrinkage and low birefringence. Also disclosed are electronic display cells made using such polyglutarimide substrates.

Plastic substrates for electronic display applications

Acrylic impact modifiers for polar thermoplastics such as poly(methyl methacrylate), polyamides, and poly(vinyl chloride) are prepared from emulsion polymer particles with hard methacrylate-rich domains in a continuous polyacrylate network.
