Mixtures of at least one dialkylphosphinic acid with at least one other dialkylphosphinic acid that is different therefrom, method for production thereof, and use thereof.
The invention relates to a mixture of at least one dialkylphosphinic acid of the formula (I)
in which
R1, R2 are the same or different and are each C1-C18-alkyl, C2-C18-alkenyl, C6-C18-aryl, C7-C18-alkylaryl,
with at least one different dialkylphosphinic acid of the formula (II)
in which
R3, R4 are the same or different and are each C1-C18-alkyl, C2-C18-alkenyl, C6-C18-aryl and/or C7-C18-alkylaryl,
with the proviso that at least one of the R3 and R4 radicals is different than R1 and R2.

The present invention relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least one flame-retardant substance (FD1) chosen from a phosphorus-based additive.
In particular the present invention it relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least one flame-retardant substance (FD1) chosen from a phosphorus-based additive that can be used as a syrup and especially as a syrup for impregnation and for the preparation for improving the fire resistance of a thermoplastic polymer or matrix obtained after polymerization of the syrup. Also concerned is a thermoplastic material obtained after polymerization of the liquid composition or syrup. The invention also relates to a process for manufacturing such a liquid composition or syrup. The invention also relates to a process for impregnating a fibrous substrate of long fibers with said liquid composition or syrup. The invention also relates to a fibrous substrate preimpregnated with said liquid composition or syrup which is useful for manufacturing composite parts.
The present invention also relates to a process for manufacturing mechanical parts or structural elements made of composite material and to mechanical parts or structural elements made of composite material obtained via a process using such a liquid composition.
