(page 6, line 48 - page 8, line 2). Diamide compounds of formula (D-1), e.g., adipic acid dianilide and
itaconic acid dianilide, are preferred (page 7, lines 44-45). Using less than 20% by weight
polyphenylene ether resin (b) or less than 4% by weight of the hydrogenated alkenyl aromatic
compound/conjugated diene block copolymer (c) reduces organic solvent resistance and impact
strength, respectively, to unsatisfactory levels (page 7, lines 53-63).I. Composition claims
Claim 1 recites a crystalline polypropylene resin consisting essentially of crystalline propylene
resin and a specified diamide ß-nucleating agent. According to the examiner, it would have been
obvious “to eliminate any of the resinous components of the blend [of Shibuya]... if the concurrent
mechanical properties associated therewith were not desired” (answer, page 3).
However, based on the resin described by Shibuya, a person having ordinary skill in the art would not
have had any reason or motivation to prepare a resin composition according to Shibuya which does not
