ABSTRACT:
Polysiloxanes containing hydroxyl groups are manufactured by reacting polysiloxanes, which have been (so-called) advanced with polyols and which contain alkoxy groups, with aliphatic or cycloaliphatic diols in the presence of a catalyst at elevated temperatures. The new polysiloxanols can be used as modifiers for organic resins such as urethane resins or epoxide resins, and give flexible, hydrophobic plastics having valuable mechanical properties.
