Proposing new market value with proprietary controlled radical polymerization technology

Pursuing core competences through open innovation

The Advanced Polymer Laboratory is conducting research and development in the ﬁeld of functional polymer
materials using the TERP method: a proprietary controlled radical polymerization method developed in collaboration with Yamago Laboratory, Kyoto University. The TERP method is characterized by its advanced molecularweight control, wide-ranging versatility that allows it to be applied to various monomers, and high functionalgroup resistance. These characteristics make it possible to design various functional polymer materials with newproperties that did not previously exist. So far wehave developed applications such as adhesives thattake advantage of the features of molecular weightcontrol in the high molecular weight domain, andpigment dispersants that can be created in a wide
range of designs utilizing monomer versatility inblock copolymer synthesis, which is another featureof controlled radical polymerization. These products
have been launched onto the market under the
TERPLUS brand name.
We are also developing commercial production
processes utilizing pilot facilities at a dedicated

diversity. Currently Otsuka Chemical accepts employees from overseas subsidiaries foraround two weeks, and conducts training programs to improve their understanding of the
Otsuka Group and Japan. Although plans were interrupted in 2020 by the impact of the
COVID-19 pandemic, once it becomes possible to continue these activities the next

remains focused on systematic human resources development at a time when there isan urgent need for global management due to the rapid social, economic, andindustrial changes in recent years.
