The present invention relates to a method for polymerizing paste PVC and a foaming molded article. The present invention overcomes non-easiness of treatment caused by high viscosity of an existing antifoamer and a problem that paste PVC latex does not evaporate, but remains when drying, maintains physical properties of paste PVC by inputting and polymerizing a specific liquid compound to a polymerization reactor in a specific point during polymerization and can reduce polymerization time by effectively removing bubble in a reflux condenser and preventing degradation of heating efficiency, and reduces the temperature of reaching the maximum of the end of the reaction and can stably make a paste PVC resin which can be applied to manufacture the foaming molded article such as artificial leather, surface, wall paper, floor decorations, gloves, carpets, etc. |
