Method to decrease the acetaldehyde content of melt-processed polyesters |
摘要 |
A method for decreasing acetaldehyde content of melt processed polyester comprising combining with melted polyester an organic additive compound which scavenges acetaldehyde from the polyester without imparting discoloration to the polyester. The organic additive compound comprises at least two hydrogen substituted heteroatoms bonded to carbons of the organic additive compound such that the organic additive compound is reactive with acetaldehyde in the polyester to form water and a resulting organic compound comprising an unbridged five or six member ring including the at least two heteroatoms. The reduced acetaldehyde content polyester is particularly useful for making containers such as for packaging beverages. |
