ABSTRACT:
A method of preparing a dispersion of a crystalline linear saturated polyester of high molecular weight which comprises contacting said polyester with a high boiling organic liquid whose boiling point is at or above the melting point of the polyester, the weight ratio of polyester to high boiling organic liquid being between 40:60 and 60:40 and heating the resultant mixture at elevated temperature until a homogeneous mass forms, cooling the resultant mass with stirring too such an extent that the melt material is still able to flow or be stirred and then allowing the material to further cool and stiffen without further stirring; or before or during further cooling diluting the mixture while it is still capable of flowing or being stirred, with an additional amount of a high boiling organic liquid or a liquid miscible therewith and thereafter further cooling the resultant mixture.
