Patent ID: 8633262

Claim:
A polymer blend comprising: (A) about 1% by weight to about 99% by weight of at least one polymer (A) comprising: (1) a dicarboxylic acid component comprising: (a) 70 to 100 mole % of terephthalic acid residues; (b) 0 to 30 mole % of residues of at least one modifying aromatic dicarboxylic acid having up to 20 carbon atoms; and (c) 0 to 30 mole % of residues of at least one aliphatic dicarboxylic acid having up to 16 carbon atoms; and (2) a glycol component comprising: (a) 5 to 60 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and (b) 40 to 95 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 %; (B) about 1% by weight to about 99% by weight of at least one polymer (B) comprising: (1) a dicarboxylic acid component comprising: (a) 70 to 100 mole % of 1,4-cyclohexanedicarboxylic acid residues; (b) 0 to 30 mole % of residues of at least one aromatic dicarboxylic acid having up to 20 carbon atoms; and (c) 0 to 30 mole % of residues of at least one modifying aliphatic dicarboxylic acid having up to 16 carbon atoms; and (2) a glycol component comprising 50 to 100 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 (C) 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 polymer blend.
