Abstract: Abstract In this work, a novel hyperbranched poly (urethane-phosphine oxide) (HPUPO) was facilely synthesized from 4,4′-diphenylmethane diisocyanate and trihydroxymethylphosphine oxide at room temperature. When HPUPO was incorporated, flame retardancy and toughness of epoxy resin are… read more here.

Abstract: Abstract In this study, a novel hyperbranched benzoxazine (HB-PED230) was synthesized from the reaction of Jeffamine D230, 1,1,1-tris(4-hydroxyphenyl)ethane and paraformaldehyde through the simple one-step Mannich condensation reaction. The characteristic structure of oxazine ring in HB-PED230… read more here.
