Abstract
A high solids polymerization process for producing a water-soluble polymer wherein a mixture of exothermically polymerizable material in water is cooled to produce a cold syrup or crystalline slurry of the polymerizable material in a polymerizable material/water solution and said syrup or slurry is initiated to polymerization wherein the reaction is controlled by absorbing the exothermic heat of polymerization employing the sensible heat and/or the latent heat of fusion of the cooled syrup or slurry as a heat sink. This polymerization process is capable of being carried out in a batch as well as a continuous process.
