| Abstract | (57) ABSTRACT Novel high performance disilane/organosilicon resins useful, e.g., as molding powders and textile and building waterproofing agents (either in the form of aqueous dispersions or organic solutions thereof), comprise cohydrolysis/condensation reaction products in hetero geneous solvent medium of admixture of organo chlorosilanes and organochlorodisilanes, said admixture comprising: (i) from about 10 to 70 molar 9% of at least one diorgano chlorosilane having the formula R2SiCl2, in which the radicals R, which may be identical or different, are each hydrogen, methyl or phenyl; (ii) from about 30 to 70 molar 9% of at least one methyl chlorodisilane which comprises at least about 30 moles % of tetrachloro-1,2-dimethyldisilane; and (iii) from 0 to about 60 molar 9% of at least one organo trichlorosilane having the formula R'SiCl3, in which R" is defined as is R above; and said resins having an average functionality of from about 2.2 to 3. |
