Abstract
A method of preserving cellulosic material is provided. The method includes contacting the cellulosic material with a paraben-containing monomer and polymerizing the paraben-containing monomer to provide a polymer impregnated within the cellulosic material; or alternatively, first polymerizing the paraben-containing monomer to give a polymer comprising repeat units formed of the monomer and contacting the cellulosic material with the polymer under pressure to provide the polymer impregnated with the cellulosic material. Articles including the cellulosic material and at least one polymer which includes paraben moieties are also provided, such as a wooden plank, a utility pole, a railroad tie, a ship's hull, a wooden utensil, a toy, a model, a piece of furniture, a vehicle, or a serving dish.
