Abstract
The invention comprises silanes of the formula <FORM:0761505/IV(a)/1> where R is chlorine or an alkoxy radical of 1 to 5 carbon atoms, and polysiloxanes derived therefrom. The silanes are prepared by reacting hexachlorocyclopentadiene with vinyl trichloro- or vinyl trialkoxy silane. The reaction may be effected between about 75 DEG and 250 DEG C. in the presence of an inert solvent or in the absence of a solvent. The trialkoxy silanes may also be prepared by reacting the trichloro silane with absolute ethanol. The examples describe the preparation of [1,2,3,4,7,7-hexachlorobicyclo-(2.2.1) - 2 - heptenyl - 5] - triethoxy - and trichloro-silanes. By hydrolysing only two R groups in the monomer, linear polysiloxanes of the formula <FORM:0761505/IV(a)/2> are obtained, R being as above defined and X being the 1,2,3,4,7,7-hexachlorobicyclo-(2.2.1)-2-heptenyl-5 radical. Complete hydrolysis yields cross-linked polymers having an X/Si ratio of 1. The silanes may also be cohydrolysed with other silanes, e.g. dimethyl silane diol. Hydrolysis is effected by water in the presence or absence of a solvent, with or without heating. The polymers are useful as ingredients in fireproofing agents, water-repellent compositions, impregnants for laminations, hydraulic fluids and low temperature lubricants.
