Organo-mineral polycondensate and process for its preparation.

摘要

Organo-inorganic polycondensate, characterised in that it corresponds to the formula CvHwOxSiyMez with: v = 4 to 48 w = 5 to 52 x = 5 to 48 y = 2 to 16 z = 1 the v/(y + z) ratio being less than 7, CvHw being a carbon chain carried by the silicon, and Me being a metal or a mixture of metals chosen from groups IVA, VA, VIA, IIIB or IVB of the periodic classification.
