Appeal No. 2000-0343
Application 08/849,008
dissolving the ethylenically unsaturated carboxylic acid or
anhydride in a nonaqueous solvent and impregnating the filler
with this solution, and does not disclose modifying by
irradiation or fluorination the surface of the thermoplastic
polymer with which the coated filler is mixed.
Earl discloses a process for modifying lignocellulosic
material before it is formed into a board (col. 1, lines 42-
45). The process includes treating the lignocellulosic
material, which may be in particulate form, sequentially or
simultaneously with 1) phthalic anhydride, which may be in
solution in a nonaqueous solvent, and 2) a thermosetting
resin, and then heat curing the resulting product (col. 1,
lines 42-53 and 62-63; col. 2, lines 8-11).
Simons discloses a method for forming particle board by
impregnating natural fibrous material particles with coal tar,
pitch, asphalt or bitumen dissolved in a solvent, applying
novolac resin in finely divided form and a crosslinking agent
to the impregnated particles so that the resin adheres to the
impregnated particles, recovering the solvent, and pressing
the composition to form particle board (abstract; col. 3,
lines 31-32).
