摘要： A solution polymerization process for producing an organic polymer from styrene and at least one other polymerizable monomer comprising providing a liquid reaction medium suitable for conducting said polymerization, wherein the reaction medium contains styrene and a polymerizable monomer other than styrene; and, anionically polymerizing styrene and monomer, thereby forming random copolymer chains, wherein the total quantity of said styrene used in said polymerization is at least 50% by weight based on the total weight of styrene and other polymerizable monomers used in the polymerization. A second embodiment comprises a copolymer made by the above-described method.A third embodiment comprises a process for forming a toner, wherein the process comprises providing a liquid reaction medium suitable for conducting a solution polymerization, the reaction medium containing at least two polymerizable monomers; anionically polymerizing the monomers, thereby forming random and nearly random copolymer chains; finely dividing the copolymer into particles; and, incorporating said particles into a composition for use as a toner. A fourth embodiment comprises a toner made by extrusion with pigment or colorant and change control additive to form small particles.A fifth embodiment comprises a solution polymerization process for producing an organic polymer wherein a difunctional initiator is used to initiate said polymerization.

摘要： Unsaturated linear polymers have repeating units of a reaction product of a first monomer, a second monomer, a third monomer and optionally a fourth monomer. The linear polymers have a glass transition temperature ranging from about 52.degree. C. to about 61.degree. C. The first monomer should have a weight average molecular weight less than 200. The second monomer may be a dicarboxylic acid or diester which is different than the third monomer. A concentration of second residues of the polymer, derived from the second monomer, ranges from about 3 wt. % to about 15 wt. %, based on the total weight of the polymer. The third monomer is an aromatic dicarboxylic acid or an ester thereof. In the polymer, a concentration of third residues, derived from the third monomer, ranges from about 40 wt. % to about 55 wt. %, based on the total weight of the polymer. The fourth monomer is a diol having a higher molecular weight than the first monomer. In a process for preparing the inventive polymer, the first, second, third monomer (and optionally a fourth monomer) and/or a catalyst undergo transesterification to form the unsaturated, linear polymer.
