Definitions

Figure 3 shows a comparison of the neck-in observed for a polyester composition without addition of inorganic filler (left bar on graph) and with addition of 10% CaCO (right bar on graph), at an extrusion coating line speed of 400 fpm.
polyester composition according to the present invention may be a polymer, copolymer, or blends thereof.
polymers refers to polyesters obtained by polycondensation reaction and having residues from starting materials comprising a dicarboxylic acid and a diol.
the dicarboxylic acid is an aromatic dicarboxylic acid such as terephthalic acid or naphthalene-2,6-dicarboxylic acid or an ester thereof.
the diol is an aliphatic glycol.
the polyester may contain other particles in amounts not adversely affecting the advantageous effects of the present invention.
the polyester may contain fine particles of amorphous zeolite, anatase titanum dioxide, calcium phosphate, silica, kaolin clay, talc, and the like.
the polyester composition may contain fine catalyst particles precipitated by the esterification reaction. The amount of these additional materials may be less than about 1 weight % of the total polyester composition.
