METHOD FOR PRODUCING AN OPTICAL ROD-SHAPED GRADED-INDEX POLYMER PREFORM, PREFORM OBTAINED IN ACCORDANCE WITH THIS METHOD AND OPTICAL LENS AND OPTICAL FIBRE OBTAINED BY USING SAME

摘要

A kind of manufacture rodlike graded-index polymer of optical precast product is by making near composition prefabricated component core with the housing component of composition by including initial substance with rotated mixture, it thus include the distribution and monomer that the rotation of various monomer mixtures is realized as follows later, polymerization is by rotating the mixture, or a kind of monomer mixture of thermoplastic polymer, the monomer with from the polymer be monomer preparation, it is rotatable, and distribute the monomer and polymer realizing, the monomer is present in the mixture then polymerization and rotation, rotation is by the relevant rotation speed of diameter in the case of two of them, by following general equation: 10,000 rev/min of ＞ d-0.5, in which:=rev/min revolving speed, the diameter (centimetre) of turnover number d=prefabricated component per minute. The invention additionally relates to the polymer that optical lens and optic fiber preformed article are formed therefore to generate.
