ABSTRACT:
An apparatus for producing a light transmitting article of synthetic resin in which a monomer Ma is incompletely polymerized to form a network polymer Pa having a refractive index Na, thereby forming a self supporting body material, and subsequently a monomer Mb, which forms a polymer Pb having a refractive index Nb different from the refractive index Na, is diffused into the body material and simultaneously polymerized. The apparatus includes a mold in which the body material is formed, a diffusion chamber in which the monomer Mb is diffused into the body material, and a heat-treating tube for heating the body material so that the distribution of the monomer Mb is fixed in the body material. According to the invention, a light transmitting article of synthetic resin is produced continuously in good quality.
