The invention relates to novel fusible zinc phosphinates of the formula (I) and/or polymers thereof where R<1 >and R<2 >are identical or different, and are hydrogen, C1-C6-alkyl, linear or branched, and/or aryl, which have a melting point below 250° C. The invention further relates to a process for preparing these zinc phosphinates, and also to their use as flame retardants in thermoplastics and in moldings, films, filaments, fibers, woven materials, or knitted materials produced therefrom.
