Abstract: A method of making a window panel with a synthetic resin frame comprising forming a synthetic resin frame by extruding synthetic resin through a die into a specified shape along a peripheral portion of a plate-like material for a window on at least one surface of the plate-like material, and curing the formed synthetic resin frame so that the synthetic resin frame is formed integrally with the peripheral portion of the plate-like material, characterized in that the die is moved to trace a locus along a peripheral portion of the plate-like material which has been previously inputted, and the locus and the angular position of the die are corrected by detecting a position of the end face of the plate-like material, whereby the synthetic resin frame having a specified shape is formed.

Abstract: A reaction curable composition comprising, as reactive materials, a polyisocyanate component comprising a diisocyanate and a tri or higher functional polyisocyanate and having an average equivalent molecular weight of from 120 to 240, and a polyol component comprising a diol and a tri or higher functional polyol and having an average equivalent molecular weight of from 100 to 550.

Abstract: A method for producing a sheet or film of a transparent synthetic resin, which comprises discharging onto a continuous substrate moving in one direction a synthetic resin material for the transparent synthetic resin from a discharge die having a linear outlet extending perpendicular to the moving direction of the substrate, casting and curing or solidifying the resin material on the substrate to form a sheet or film of the transparent synthetic resin, wherein the discharge die is continuously or intermittently reciprocated in a direction substantially perpendicular to the moving direction of the substrate.
