LAYERED SILICATE GLYCOL DISPERSION, PREPARATION THEREOF, AND POLYESTER POLYMER COMPOSITION OBTAINED THEREBY

摘要

PURPOSE: Provided is a layered silicate glycol dispersion, which improves the inter-layer separation of layered silicate and the intra-layer insertion of ethylene glycol, thereby improving the dispersion of layered silicate in a polyester polymer composition. CONSTITUTION: The glycol dispersion is based on a glycol component in which a layered silicate is dispersed in the state that the layers are uniformly separated, wherein the concentration of the layered silicate is 1-30 wt% and at least one inorganic or organic particles having the average particle diameter of 0.005-5 micrometers are dispersed in addition to the layered silicate. The inorganic or organic particles are present in the amount of 0.1-1.0 wt% based on the weight of the layered silicate.
