APPENDIX
Claim 1. A process for making substantially homogeneous
polymers of at least two monomers having substantially
differing reactivity rates, in a selected composition, by
polymerization of said monomers, comprising:
(a) precharging all of the slowest reacting monomer in an
amount in accordance with the selected composition, optionally
with part of one or more of said faster reacting monomers, and
(b) introducing the faster reacting monomer or monomers
independently and incrementally or continuously into the
reactor at a specific feeding schedule for each monomer, as
determined for each monomer before the polymerization by the
following equations:
where A (t) has four adjustable parameters, a , a , a and aj 1 2 3 4
for each monomer:
and
a determines the center of the distribution;
1
a affects the width of the distribution;
2
a determines the ascending portion of the distribution;
3
and
