Patent ID: 8309624

Claim:
A blend comprising about 80% by weight to about 99.99% by weight of at least one polyester comprising: (a) a dicarboxylic acid component comprising: (i) 70 to 100 mole % of residues of terephthalic acid or an ester thereof; (ii) 0 to 30 mole % of residues of at least one aromatic dicarboxylic acid having up to 20 carbon atoms; and (iii) 0 to 30 mole % of residues of at least one modifying aliphatic dicarboxylic acid having up to 16 carbon atoms; and (b) a glycol component comprising: (i) 10 to 40 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and (ii) 60 to 90 mole % of 1,4-cyclohexanedimethanol residues, wherein the total mole % of the dicarboxylic acid component is 100 mole %, and the total mole % of the glycol component is 100 mole %; and about 0.01% by weight to about 20% by weight of at least one antimicrobial agent chosen from at least one of: silver oxides, silver zirconium phosphates, silver glass, silver silicas, or combinations thereof; said weight percentages being based on the total weight of the blend.
