Abstract: A system, including apparatuses and methods, and a service employing such system for identifying opportunities and enabling persons to become associated with opportunities in which persons can make an impact, for identifying individual and collective synergies and commonalities between persons, opportunities, organizations, groups and partners, for capturing and monitoring the impact of persons associated in opportunities, and for visually presenting the impact of persons, opportunities, organizations, and the system through multi-level aggregation, or roll-up, of key performance indicator data. The system orders synergistic matches and permits user selection, via a slider control, of the extent of synergy to be used in selecting and displaying matches. The system also permits the custom weighting of key performance indicators, or metrics, by different users to account for the relative importance of various metrics to such different users.

Abstract: This invention is a process to manufacture high quality vinyl aromatic polymer that is essentially free of unreacted vinyl aromatic monomer using retarded anionic polymerization wherein the retardant is insoluble and can be removed from the polymerization at an intermediate stage so that the polymerization can be carried to completion in the absence of the retardant.

Abstract: The present invention is an improvement in a free radical bulk polymerization process for preparing a high molecular weight polymer from a vinyl aromatic monomer characterized in that the polymerization is conducted in the presence of an acid catalyst having a pKa at 25.degree. C. of less than 2, or salt thereof, wherein the improvement comprises dispersing the acid catalyst, or salt thereof, in a (meth)acrylic acid or ester thereof, prior to contact with the vinyl aromatic monomer. The (meth)acrylic acid or ester allows the acid catalyst to be dispersed within the vinyl aromatic monomer without causing cationic polymerization. The acid catalyst, or salt thereof, catalyzes the free radical polymerization reaction such that high molecular weight polymers are produced in reasonable reaction times.

Abstract: The present invention is a free radical bulk polymerization process for producing a rubber modified polymer from a vinyl aromatic monomer comprising:polymerizing the vinyl aromatic monomer in the presence of a diene rubber having at least one stable free radical group, under polymerization conditions such that a vinyl aromatic-diene block and/or graft copolymer rubber is formed.

Abstract: A process is disclosed whereby a polymeric resin (containing ester and/or carbonate bonds) is readily converted into a resin having a modified molecular structure. Accordingly, a polycyclic carbonate (a monomer or oligomer) is transesterified with the polymer resin in the melt, preferably upon extrusion, optionally in the presence of a catalyst. Significantly, the cyclic carbonates are, by the inventive process, inserted into the structure of the polymer, effecting branching of the molecular structure, a branching which manifests itself in the modified properties of the resin.
