Abstract: Hyperbranched polytetrazole exhibited good electrical conductivity;semi-crystalline hyperbranched poly(ester-amide)s with suitable glass transition temperature (T_g) and melting temperature (T_m) can be good candidate for UV-curable powder coatings; a series of sulfur-containing hyperbranched polymeric photoinitiators end-capped with tertiary amine moieties (B/A-HPIs) were synthesized, which showed much higher photoinitiating reactivity. This paper will summarize hyperbranched polymers application in the new materials field from these three aspects.

Key words: hyperbranched, electrical conductivity, UV-curable powder coatings, polymeric photoinitiators
