Appeal No. 2002-0701
Application 09/201,269
having a low vapor pressure, preferably maleic anhydride,7 and a
peroxide initiator to reduce the monomer content (col. 2,
lines 10-16 and 28-29; col. 3, lines 38-39 and 52-58). Two
disclosed initiators having a half-life between 0.5 minutes and
2 hours at the reaction temperature are tert-butylperoxyisopropyl
carbonate (col. 3, line 45), which is one of the appellant’s
initiators (specification, page 13, line 22), and di-tert-butyl
peroxide (col. 3, lines 45-46), which is one of the initiators of
the appellant (specification, page 13, line 10) and Houser
(col. 3, line 54).
Oshima discloses a resin composition comprising a
polyphenylene ether resin, a thermoplastic polyester resin, and
two components for compatibilizing these resins, one of which is
an organic peroxide having a half life of one minute at
temperatures ranging from 100º to 270ºC (col. 2, lines 1-19;
col. 7, lines 14-20). The resin composition is for use in making
molded articles having high mechanical strength, especially high
impact resistance (col. 1, lines 53-57).
7 Maleic anhydride is Margotte’s only disclosed low vapor
pressure monomer.
