Publication number: 20030046783Abstract: The present invention relates generally to a polyvinyl acetate (PVA) sponge. More specifically, a PVA sponge according to the present invention has certain improved physical characteristics, such as uniform pore size, a microscopically rough surface, and/or a neutral surface charge. Certain characteristics may be achieved by a variety of methods in which pore-forming chemicals are dissolved into a PVA solution, so that no solid residues remain in the pores of a PVA sponge after production. Neutral surface charge of a PVA sponge may be achieved by adding a charge modifying agent during the sponge making process.Type: ApplicationFiled: September 10, 2001Publication date: March 13, 2003Inventors: Guangshun Chen, Xingbo Yang
