摘要：
Complexes of copper and/or zinc with hydrolyzed olefin/maleic anhydride copolymers were solubilized in ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.
