| titleOfInvention | The method of producing linear polycarbosilanes PL |
| abstract | A method for the preparation of linear polycarbosilanes of the formula Y- [(CH2) m -Si (Me) 2] n-X, wherein Me is a CH3 group, Y is a hydrogen atom or a trimethylsilyl group, X is a chlorine atom; OR or NHR group, where R is a hydrogen atom, an alkyl or silyl group substituted with alkyl groups, m = 1 or 3, and n = 10-250 by polymerization of silaalkanes in the presence of a catalyst, characterized in that a cyclic tetrafluoroalkan is polymerized at a temperature of 50-110 ° C, with a catalyst selected from the group consisting of PtO2, Pd / C or (C5 H5) M, where M is a transition metal of group VB, VIB, VIIB or VIII, with a catalyst to monomer molar ratio of 2x10-2 And after completion of the process, optionally a low molecular weight compound of formula XY, wherein X and Y are as defined above, preferably selected from the group consisting of chlorosilanes, alkoxysilanes, hydrosilanes, siloxanes or silazanes.
