Polymerization processes

Abstract

A process for preparing a polymer comprising selecting temperatures and amounts of a polymerization medium, a surfactant, a monomer or polymer seed, and any desired additives to achieve an initial temperature in a polymerization reactor; adding the polymerization medium and surfactant as contents to the polymerization reactor whereby the surfactant is added within 1.5 times a time period required for polymerization medium addition; and introducing the monomer or polymer seed and the any desired additives as contents to the polymerization reactor, wherein the temperatures and amounts of the contents are selected such that when the additions are completed, the resulting temperature of the contents of the polymerization reactor is within about 5° C. of a temperature at which polymerization is initiated, and wherein less than about 5 kcal of energy is removed or added per liter of contents in the reactor; and initiating polymerization.
