Abstract
Official abstract text for this publication.
The present disclosure describes a treated cellulosic material comprising: a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising: a polymer comprising an olefin-carboxylic acid copolymer; and a modifying agent comprising a hydrophobic amine.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing a treated cellulosic material comprising: (a) providing a cellulosic material, the cellulosic material comprising wood; (b) a first treatment protocol comprising impregnating the cellulosic material with an aqueous dispersion comprising a polymer, the polymer comprising an olefin-carboxylic acid copolymer wherein at least a portion of the carboxylic acid groups of the copolymer are neutralized; and (c) a second treatment protocol comprising impregnating the cellulosic material with a modifying agent comprising N-methyl N-hexylamine, N,N-diethyl n-hexylamine, n-octylamine, n-decylamine n-dodecylamine, N-methyl cyclohexylamine, N,N,-diethyl cyclohexylamine, dicyclohexylamine, benzylamine, cocoamine, oleylamine, stearylamine, an N, N-dimethyl substituted fatty amine, phenethylamine or tallowamine. 2. The method of claim 1 , wherein the impregnating of the first treatment protocol is conducted wider pressure greater than or lower than ambient. 3. The method of claim 1 , wherein the polymer is ethylene-acrylic acid copolymer.
