Reaction products of polysiloxanes and polyphenols |
摘要 |
Reaction products, containing phenolic hydroxyl groups, of polysiloxanes and polyphenols are obtained by reacting alkoxy-terminated or acyloxy-terminated polysiloxane compounds with polyphenols at elevated temperature, employing 1.2 to 10 equivalents of phenolic hydroxyl groups per 1 equivalent of alkoxy group or acyloxy group. The reaction products containing hydroxyl groups can be used for curing and modifying epoxide resins and give flexible, hydrophobic plastics of valuable mechanical and dielectric properties.
