<p>PURPOSE:To quickly and homogeneously introduce a polymerizable compound into a polymer-molded product matrix while retaining the shape of the molded product by employing as an introducing solvent a supercritical fluid prepared by converting into the supercritical state a substance which is a gas at the standard state. CONSTITUTION:A polymerizable compound of liquid state and/or solid state is dissolved in a supercritical fluid prepared by making a substance which is gaseous in the standard state (e.g. CO2, ethylene, etc.) into a state of supercritical temp, and supercritical pressure. The introducing solution prepared thus is brought into contact with a polymer molded product to introduce the polymerizable compound into the polymer-molded product matrix. In an embodi ment, a polymer-molded product and a polymerizable compound are received in a pressure-resistant introduction container 1 having a temperature-controlling function and an introducing solvent such as CO2 from an introducing solvent storage tank 2 is supplied into the introducing container 1. The temperature and inner pressure of the introducing container 1 are controlled to convert the introducing solvent into a supercritical state.</p> |
