Abstract:
A composition containing organotin maleates as obtained by the reaction of a mixture composed of at least one component RA and at least one component R.sup.1 A with maleic anhydride and then bringing the reaction mixture thus obtained into reactive contact with at least one dialkyltin oxide (R.sup.2).sub.2 Sn.dbd.O, or with at least one alkyltin chloride (R.sup.2).sub.x SnCl.sub.4-x wherein:RA representseither an alcohol ROH in which R represents a linear or branched aliphatic hydrocarbon radical having a number of carbon atoms of 1 to 10 or a mixture of alcohols with a weight-average molecular mass Mw greater than 32 and not more than 158,or an epoxyalkane C.sub.n H.sub.2n O in which n is 1 to 10 or a mixture of epoxyalkanes with a weight-average molecular mass Mw greater than 30 and not more than 156;R.sup.1 A representseither an alcohol R.sup.1 OH in which R.sup.1 represents a linear or branched aliphatic hydrocarbon radical having a number of carbon atoms of 20 to 50 or a mixture of saturated primary alcohols with a weight-average molecular mass Mw of 298 to 718,or an epoxyalkane C.sub.p H.sub.2p O in which p is 20 to 50 or a mixture of epoxyalkanes with a weight-average molecular mass Mw of 296 to 716;R.sup.2 represents a linear or branched aliphatic hydrocarbon radical having a number of carbon atoms of 1 to 12,x is an integer equal to 1 or 2.
