摘要：

Resins were prepared from resoles and Pinus pinaster bark tannins by copolymerization at room temperature. Reducing the moisture content of the tannins to below 60% increased their stability, so allowing preparation of the resin before its application. Various formulations were tested, all of them substituting 50% of phenols by tannins. The resins obtained were used to manufacture 5-plyeucalyptus boards which met BS 1455:1963 WBP quality standards.
