    Abstract: The present invention provides among other things methods for preparing polymeric reagents, wherein the method comprises (a) providing an aromatic moiety bearing a hydroxy group, a first amino group and a second amino group; (b) reacting a functional group reagent with the hydroxy group to result in a hydroxy group bearing a functional group capable of reacting with an amino group of an active agent and resulting in a hydrolyzable carbamate; and (c) reacting a plurality of poly(alkylene glycol) water-soluble polymers bearing a reactive group with the first amino group and second amino group to result in (i) a first amino group bearing a water-soluble polymer through a spacer moiety, and (ii) a second amino group bearing a second water-soluble polymer through a spacer moiety.

    Abstract: This invention relates to polyester compositions useful for the manufacturing containers that minimizes the effect of secondary contamination during filling. More specifically, the present invention relates to a polyester bottle for use in filling of carbonated pasteurized products comprising at least one oxygen scavenging component that limits oxygen ingress to about 1 ppm or less when measured six months after filling, and at least one passive component that limits the carbonation loss to less than about 25% when measured six months after filing. The present invention also relates to a method of using the polyester bottle to minimize the growth of secondary contaminants in a carbonated pasteurized product.
