PROCESSO PARA SAPONIFICAR POLIMEROS DE ETILENO/ACETATO DE VINILA |
摘要 |
A process for the production of saponified ethylene-vinyl acetate interpolymers into spherical particles having a number average particle size of about 10 microns or less is provided when a strong inorganic base is used as the saponification agent and a particular ethylene oxide-propylene oxide block copolymer is used as the dispersing agent, by reducing the amount of the residual salt in the product resin to less than about 0.1% calculated as the cation. |
