Appeal No. 1995-4810
Application No. 08/011,499
The composition of appealed claim 12 requires certain
amounts of at least three components, i.e., PPS, a polyamide
prepared by polycondensation of adipic acid with
m-xylylenediamine (e.g., PAMXD6, see the specification, page
4, lines 20-25), and magnesium hydroxide.
The examiner finds that the Abstract discloses polymer
blends of PPS and a polyamide with additional filler, such as4
aluminum hydroxide, to “provide sealing compositions for
electronic parts which deter water seepage between the
interfaces of wire and polymer.” (Answer, page 4). The
examiner further finds that Ohara discloses that magnesium
hydroxide used in conjunction with glass fibers in PPS
compositions for electronic parts yields excellent arc
resistance for these compositions, as opposed to the results
for aluminum hydroxide (Id.). Finally, the examiner applies
Williams for the teaching that magnesium hydroxide provides
good electrical tracking resistance when used in polyamide
compositions (Id.). From these findings, the examiner
4Actually the Abstract only discloses a "polyarylene
sulphide" resin composition (see lines 1, 2 and 3 of the
Abstract).
