ABSTRACT:
Bisphosphine oxide monomers and homologs thereof may be incorporated into polycarbonates in order to obtain a flame retardant polymer. More particularly, bis[2,5-(diphenylphosphine oxide)]-1,4-hydroquinone and homologs thereof may be used to prepare flame retardant polycarbonates that retain high glass transition temperature and high impact resistances.
