Phosphinate flame retardant and process for manufacture thereof

A phosphinate or a composition of phosphinates obtainable or obtained by reacting at least a phosphinic acid of formula (I) with an oxirane of formula (II): wherein R1 and R2 are the same or different and independently represent H or a hydrocarbyl radical, with the exception that R1 and R2 may not e...

Beschreibung
Zusammenfassung:	A phosphinate or a composition of phosphinates obtainable or obtained by reacting at least a phosphinic acid of formula (I) with an oxirane of formula (II): wherein R1 and R2 are the same or different and independently represent H or a hydrocarbyl radical, with the exception that R1 and R2 may not each be H at the same time and with the hydrocarbyl radical selected from C1-C10 alkyl groups, and wherein R3 is an alkylenyl group which is optionally substituted with a heteroatom selected from O, N and S. The phosphinate or phosphinate composition thus obtained can be used as reactive or additive flame retardant, to manufacture flame-retardant polymers or flame-retardant polymer compositions.
