Appeal No. 1997-2344
Application No. 08/273,550
Claims 1, 7, 8, and 9 are representative and are
reproduced below:
1. A method for promoting crystallization from the melt
of a semi-crystalline polyolefin copolymer which comprises
adding to said copolymer an effective amount of a nucleating
package consisting essentially of a high melt flow
polypropylene having a melt flow of > 8 dg/min. and
stearamide, wherein said effective amount of nucleating
package ranges from about 0.1 to about 3 wt% of the total
composition.
7. A method for promoting crystallization from the melt
of butene-1-ethylene copolymer which comprises adding to said
copolymer from about 0.25 to about 2 wt% of a nucleating
package consisting essentially of high melt flow polypropylene
having a melt flow of from 45 dg/min and stearamide.
8. A method as in claim 7 wherein from about 0.1 to 0.5
wt% of said oxidized high density polyethylene is added in a1
slurry water bath.
9. An improved melt crystallizable composition comprising
a semi-crystalline polyolefin copolymer and from about 0.1 to
about 3 wt% of the total composition a nucleating package
consisting essentially of high melt flow polypropylene having
a melt flow of > 8 dg/min. and stearamide.
The reference of record relied upon by the examiner is:
Hwo et al. (Hwo) 4,359,544 Nov. 16, 1982
1Antecedent basis is not present in independent claim 7
for the claim language “said oxidized high density
polyethylene” in claim 8. The examiner should insure
correction of this matter in any subsequent prosecution of
this application.
