Appeal No. 95-3464
Application 08/075,857
This is an appeal from the examiner’s refusal to allow
claims 6-9 as amended after final rejection. These are all of
the claims remaining in the application.
THE INVENTION
Appellants’ claimed invention is directed toward a method
for preparing molded articles of a crosslinked olefin wherein
crosslinking takes place in the molding machine. The articles
are made from a blend of polyolefin granules which contain a
hydrosilylation catalyst, polyolefin granules which contain a
copolymer of an alkenylsilane of a recited formula and an
olefin, and optionally polyolefin granules which contain
neither the hydrosilylation catalyst nor the copolymer of the
alkenylsilane and the olefin. Claim 6 is illustrative and
reads as follows:
6. A method for preparing molded articles of a
crosslinked polyolefin which comprises the steps of mixing two
kinds of polyolefin granules comprising polyolefin granules
containing a hydrosilylation catalyst and polyolefin granules
containing a copolymer of an alkenylsilane and an olefin, or
three kinds of polyolefin granules comprising said two kinds
of polyolefin graules and polyolefin granules containing
neither the hydrosilylation catalyst nor the copolymer of the
alkenylsilane and the olefin, and then heating, melting and
molding the mixture in a molding machine whereby a
crosslinking reaction occurs in the molding machine so as to
obtain a crosslinked article in the absence of contact with
water, said alkenylsilane having the formula:
