POLYSILOXANE COMPOUNDS CONTAINING HYDROXYL GROUPS

摘要

Polysiloxanes containing hydroxyl groups are manufactured by reacting polysiloxanes containing alkoxy groups with aliphatic or cycloaliphatic-aliphatic 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.
