Abstract:

Methods for making a heterogeneous polymer blend comprising one or more anionic polymers, one or more cationic polymers, and one or more non-ionic polymers, which method comprises (a) adding to a non-neutral solution a first amount of polymerization initiator and one or more anionic or cationic monomers, wherein each monomer has the same charge; (b) a second amount of the polymerization initiator and one or more non-ionic monomers; (c) adding a third amount of the polymerization initiator and one or more ionic monomers that are oppositely charged from the monomers of (a); adding stepwise, a fourth amount of the polymerization initiator to react any residual monomer, and (e) neutralizing the resulting polymer blend. Also claimed are heterogeneous polymer blends containing polymers formed from one or more anionic, cationic, and non-ionic monomers, either polymerized in situ or separately and then combined.

International Classification:

G06F017/60

US Classification:

705/001000

Abstract:

A method and system for administering a benefit plan for a sponsor with a widely diverse participant population. Using a combination of Internet enabled tools and databases, participants can enter and confirm their own data. Plan sponsors can view that information with reference to plan parameters and guidelines coded into the benefit plan. Databases contain the plan choices, sponsor's rules, and who has access to which information. The system computes liabilities owed by the sponsor, assets used to informally fund those liabilities, and cost recovery opportunities, if any. The browser enabled system uses the advantages of the Worldwide Web (and any thin-client intranet on the sponsor's site) as its primary contact tool, with alternatives of telephone, modem, or fax. Financial information is provided to the plan sponsor as participants make choices, provides payout options to the participants, and provides considerably more interactivity than prior methods of servicing employee benefits.

Also claimed are heterogeneous polymer blends containing polymers formed from one or more anionic, cationic, and non-ionic monomers, either polymerized in situ or separately and then combined. Also claimed are methods for increasing the filler content of paper or paperboard, which methods comprises (a) combining the heterogeneous polymer blend with a precipitated calcium carbonate filler; (b) combining the resulting mixture with a pulp slurry; and (c) processing the resulting slurry mixture to form a sheet of paper or paperboard. Finally, also claimed are methods of increasing the filler content of paper or paperboard, which method comprises (1) combining either the heterogeneous blend or the precipitated calcium carbonate filler with a pulp slurry, (2) combining the remaining component with the pulp slurry; and (c) processing the resulting pulp slurry mixture to form a sheet of paper or paperboard.
