  • Patent number: 8841473
    Abstract: 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.
    Type: Grant

  • Publication number: 20120165565
    Abstract: The subject of invention is the method of synthesis of fluorocarbofunctional alkoxysilanes and chlorosilanes of the general formula HCF2(CF2)n(CH2)mOC3H7SiR1R2R3 in which -n takes values from 1 to 12, m takes values from 1 to 4,—R1 stands for an alkoxy group or halogen, if R1 stands for an alkoxy group, then R2 and R3 can be the same or different and stand for an alkoxy group containing C=1-4, alkyl group containing C=1-12 or an aryl group, if R1 stands for a halogen, then R2 and R3 can be the same or different and stand for based on hydrosilylation of an appropriate fluoroalkyl-allyl ether with an appropriate trisubstituted silane of the general formula HSiR1R2R3 in the presence of siloxide rhodium complex [{Rh(OSiMe3)(cod)}2] as a catalyst.
