This invention discloses a high clarity, low haze polyester having improved heat-up rates which contains a very small amount of an infrared absorbent material, such as carbon black. This polyester is very useful as a material for making preforms for trays, containers, and the like. It is especially useful as a material from which beverage bottles can be made.

High clarity, low haze polyesters having reduced infrared heat-up times

A high clarity, low haze polyester having improved heat-up rates contain very small amounts of an infrared absorbent material therein such as carbon black. Such polyesters are used in preforms as for making trays, etc., and especially in molding operations such as in the blow molding of beverage bottles.

A process for reducing the glycol ether content in polyesters involves adding a glycol to a polyester oligomer solution prior to polymerization, distilling the oligomer solution to remove vapor containing the glycol as well as the glycol ether, and polymerizing the solution to produce a polyester containing a reduced glycol ether content.

Reduction of glycol ethers in polyesters

Substrates such as polyethylene terephthalate copolymers are treated with polyester adhesives containing flame retardant polymers. The adhesive/polyethylene terephthalate composite possesses improved resistance to combustion.
