crystalline polyester base resin and an alkali metal salt of a
polyester polymer.

accelerator incorporated therein. According to Moritani, the
crystallization accelerators include (col. 2, lines 56-63):
2The rejection of claims 6-8 under 35 U.S.C. § 112,
second paragraph, has been withdrawn. See Paper No. 18.

appeal, claims 7 and 8 stand or fall with the patentability of
independent claim 6.
