The living radical polymerization (LRP) can obtain polymer that is controlled the molecular weight, its distribution and polymer structure precisely with keeping the versatility of the radical reaction. LRP has been expected as a fundamental technology of functional polymer synthesis to support nanotechnology.
In the field of high molecular materials, Otsuka Chemical researches about and develops various functional polymers, such as adhesives and pigment dispersants, using our unique Living Radical Polymerization technology called TERP (Tellurium mediated Radical Polymerization).
The block polymer structure realizes coexistence of the superior dispersibility and dispersion stability by controlling the sequence of components those work as an adsorption to pigment or an affinity to dispersed medium.
Advanced molecular weight control in high molecular weight area is expressed overwhelming stain resistance by decreasing the low molecular weight component which causes unwanted residue on adherend.
