Polyphosphinoboranes as PIN FRs

Polyphosphinoboranes as PIN FRs

New class of polymeric phosphorus- and boron-based PIN FRs synthetised and fire tested on cotton at lab scale. Poly(phenylphos­phinoborane) was synthesised by dehydropolymerisation of phenylphosphine-borane using an iron-based pre-catalyst in toluene, in a process...
DOPO – N PIN FR for polyamide

DOPO – N PIN FR for polyamide

A phosphorus – nitrogen PIN flame retardant was developed for PA6 providing gas phase fire performance and anti-drip. ‘CBPB’ was synthesised by reacting p-Cyanobenzaldehyde (CBAD with 2-aminobenzimidazole (2-AB), then with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-...
