Title:
METHOD FOR CRYSTALLIZING ORGANIC OLIGOMER
Document Type and Number:
Japanese Patent JP3962703
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for crystallizing in a short time an organic oligomer of low crystallization rate without using any special equipment and much energy.
SOLUTION: The method for crystallizing the organic oligomer comprises fluidizing powdery or granular organic oligomer seed crystal in an apparatus equipped with a powder agitating mechanism, and in this state, adding a liquid same kind of crystalline organic oligomer into the apparatus either continuously or batchwise to effect mixing and dispersion, thus producing the objective crystalline organic oligomer.
