AboutAbout the lab
Creating high-performance polymers that exploit the unique properties of polymers
The Polymer Chemistry Lab researches the development of polymers with high performance and functions, making use of properties unique to polymers.
Based on polymer chemistry and organic chemistry, the lab pursues both basic research and applications.
So far, the lab has developed high-performance network polymers (thermosetting resins), photosensitive polymers, and polymers with molecular recognition ability.
On the lab's website, it is introduced under the name “Oyama Lab.”
Key terms
- Thermosetting resin
- A resin that becomes a polymer with a highly crosslinked network structure when cured. It is used in adhesives, paints, and electrical and electronic materials
- Photosensitive polymer
- A polymer whose properties change in the areas exposed to light. Exposing it through a mask and developing it can produce fine patterns
- Dynamic covalent bond
- A covalent bond that can be cleaved and re-formed reversibly. It is used to rearrange the side chains of polypeptides
- Lignin
- One of the major components of plant resources. Although it is abundant, no effective way of using it has been established

ResearchResearch themes
The lab aims to develop polymers with high performance and functions by making use of properties unique to polymers. Based on polymer chemistry and organic chemistry, it pursues both basic research and applications.
*Illustrative imageDevelopment of high-performance network polymers
Cured thermosetting resins have excellent heat resistance and mechanical strength, but they are brittle. To improve this, the lab studies in situ polymerization, in which a modifier polymer is generated during curing, and interpenetrating polymer network (IPN) structures.
*Illustrative imageBiomass-derived network polymers
Lignin, a major component of plant resources, is reacted with various phenols to increase its phenolic OH groups. The lab uses the product as, for example, a curing agent for epoxy resins, and works to create high-performance biomass network polymers.
*Illustrative imagePhotosensitive polymers based on a new principle
The lab is developing “reaction development patterning (RDP),” which can give photosensitivity as is to commercial engineering plastics and similar materials. It is also expanding the range of applicable polymers and developing photosensitive polymers based on new reaction mechanisms.
*Illustrative imagePolymers that work like proteins
The lab aims for polymers that show function through properties unique to polymers, as proteins do. Using dynamic covalent bonds to rearrange the side chains of polypeptides, it is investigating how to obtain “protein-like polymers” with higher-order structure and function.
