On the other hand, there have been active experiments in adding new functions to the polymers, such as the electrical, optical, medical and biological properties. For example, copolymers which are obtained by the polymerization of ?uorine containing monomers and variety of monomers have been utilized as photoresists, optical ?ber dressings, oxygen enrichment membranes, and membrane oxygenators. Polysilane has the maximum absorption in the ultraviolet region, and also has photosensitivity; therefore, it can be used as a positive type resist with excellent oxygen plasma resistance.2) Polylactic acid (PLA) has been commercialized as an environmentally-friendly polymer, being compatible with the natural environment. Furthermore, it can save fossil resources as it is made of biomass raw materials.3)
Further broad applications are expected to be made with functional polymers, thus R&D in this ?eld is highly promising. The page below shows a wide variety of monomers and intermediates as building blocks for functional polymers. These are surely useful for the development of novel polymers.
