Composition for the preservation of wood
First Claim
1. Composition for the preservation of wood comprising a mixture of a wood preservative with a polymer composition, wherein said wood preservative is not chemically bonded to said polymer composition, and wherein said polymer composition is a polymer alloy prepared from component (a) one or more high molecular polymers possessing anhydride groups and component (b) one or more high molecular polymers containing ester groups, in which the components (a) and (b) are bonded to one another via a hydrogen bridge through complete or total protolysis of component (a).

Abstract
Composition for the preservation of wood containing a wood preservative, such as a boron compound or a fluorine compound, in a polymer or polymer composition, which upon contact with water releases the wood preservative. Said composition is introduced into a hole in the wood or in a wood construction, whereafter the hole is sealed.
