The subject of invention is the method of synthesis of fluorosilicone co-polymers of arbitrary topology and general formula 1 in which among others if A stands for CH-O(CH2)m(CF2)nCF2H group, then the method is based on hydrosilylation reaction of appropriate fluoroalkyl-allyl ether with polyhydrosiloxanes containing at least one Si-H group, catalyzed by siloxide rhodium complex. If A stands for in which Z stands for divalent group either then the method is based on the reaction of nucleophilic opening of oxirane ring in appropriate epoxyfunctional co-polysiloxanes, in acidic environment.
