Appeal No. 96-0644
Application No. 08/056,721
According to appellants, the invention is directed to a
method of forming domains of high density crosslinking in an
elastomer, and an elastomeric matrix containing sites of such
high density crosslinking (brief, page 2). Claims 1 and 6 are
illustrative of the subject matter on appeal and are
reproduced below:
1. A method for forming domains of high density
crosslinking in an elastomer matrix comprising the steps of
(a) treating textile fibers containing
hydroxyl groups with a 5% to 50%
aqueous solution of X-OH wherein X
represents a metallic cation, and
converting said hydroxyl groups to
their corresponding metal salt,
(b) reacting said metal salt with carbon
disulfide to convert said metal salt to
a xanthate having the formula
wher ein RO is the
resi due of said
text ile fiber,
(c) causing the oxidative coupling of
xanthate groups using an oxidizing
agent to form disulfurdicarbothionate
groups of the formula
