摘要：
A new group of pentaerythryl diphosphonates and of formula (I):
and poly(pentaerythryl diphosphonates) of formula (II):
are described.
Flame-retardant compositions are also described, which include a thermoplastic polymer and a certain amount of self-extinguishing agent consisting of one of the above-mentioned pentaerythryl diphosphonates or poly(pentaerythryl diphosphonates).
and poly(pentaerythryl diphosphonates) of formula (II):
are described.
Flame-retardant compositions are also described, which include a thermoplastic polymer and a certain amount of self-extinguishing agent consisting of one of the above-mentioned pentaerythryl diphosphonates or poly(pentaerythryl diphosphonates).
