Method for producing an isobutylene resin powder granules

The present invention is suspended and an object thereof is to provide a resin powder granules of isobutylene polymer was reduced residual solvent and residual monomer in the product, the isobutylene-based polymer solution, in water through the detergent After obtaining the resin slurry by removing the solvent while, 0.99 ° C. or higher, the resin was significantly reduced residual solvent and the residual styrene in the resin without quality deterioration by steam stripping at below 180 ° C. temperature It can be achieved by the process for obtaining the granules.
