摘要：
Mixed crystals comprise 100 ppmw of leavening agents and 0.1-5000 ppmw of crystallization additive. A polymer is crystallized by using the crystallization additive. The polymer is hydrophilic cellulose derivatives. An independent claim is also included for a method for preparing the mixed crystals, which involves adding crystallization additive and leavening agent during crystallization of polymer.
