Abstract:

The invention relates to compositions for reducing the swelling of wood in the presence of water, comprising: one or more polymers comprising, as polymerized units, i) 55-99.9% by weight of the total polymer of one or more (meth) acrylic acid ester monomers having the formula: wherein R=hydrogen or a methyl group; and R=an alkyl or alkenyl group containing at least 12 carbon atoms; and ii) 0.1-45% by weight of the total polymer of one or more monomers copolymerizable with (I). The invention also relates to a method of reducing the rate at which biocide leaches from wood.
