  • Method of manufacturing a light guide
    Patent number: 6673277
    Abstract: A method of manufacturing light guide by filling a polymer tube with a monomeric mixture then pressurising and heating the full length of the polymer tube to initiate and maintain polymerisation in the tube. An apparatus for performing the method is also described in which the polymer tube is placed in a reaction vessel and a temperature controlled fluid is circulated to regulate the temperature in the vessel.
