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.
