Method for manufacturing polymer rod using inclined temperature distribution and free radical bulk polymerization and method for manufacturing polymer continuous refractive index rod lens

摘要

The present invention relates to a method for producing a polymer rod and a polymer continuous refractive index rod lens using inclined temperature distribution and free radical bulk polymerization.;In the polymer rod manufacturing method of the present invention, after filling the mixed solution in which the polymerization initiator and the crosslinking agent are added to the monomer capable of radical polymerization in a tubular reaction vessel having a constant inner diameter, the upper portion is kept at a low temperature (T _L ) and the lower portion is Is maintained at a higher temperature (T _H ) than the temperature (T _L ) previously described, and the temperature gradient of (T _H -T _L ) / L (where L is the vertical length of the inclined temperature distribution region) And radically polymerizing the monomer while passing the reaction vessel described above in the retained region at a constant rate from the top to the bottom.;In addition, the method for producing a polymer continuous refractive index rod lens according to a preferred embodiment of the present invention, after immersing the polymer rod prepared by the above-mentioned process in an organic solvent and inflating it, the chemical reaction with the polymer forming the rod It includes a step of chemically reacting while diffusing a compound that can produce a polymer having a relatively low refractive index compared to the polymer through the rod.
