The continuous use temperatures in an unstressed state are generally estimated at 110°C up to 135°C for the polyester-ether grades. Polyester-esters are more resistant.

In 1973, the Federal Trade Commission modified the generic definition of polyester to include in the polyester category materials that previously were polyester ethers or benzoate polyesters. As a result, the fiber known as poly (ethylene oxybenzoate) or PEB and manufactured under the trade name A-Tell in Japan came to be known as polyester. This material is made by reacting parahydroxy-benzoic acid and ethylene oxide to give... 

Non-polar column coatings include silicone oil, hydrocarbons, and esters of high molecular weight alcohols, and dibasic acids. Polyethylene glycols, polyesters, ethers, carbohydrate esters, and derivatives of ethylenediamine are widely used polar liquid phases. 

Urethane coatings for wood surfaces, prepared with lignin-based polyester-ether-polyol, have demonstrated exceptional properties in terms of solvent and chemical resistance (18), and they provide the coated wood surface with an attractive appearance. 

The alternating polyester/ether structure was proposed also for polymers prepared from other spiroorthoesters and the following mechanism was suggested ...

Figure 2.9 Left Good adhesion between fibres and resin is demonstrated by the residual resin on the fibre surfaces after fracture. The specimen was a carbon fibre reinforced PEEK (polyester ether ketone) material. Right Exposure to hot water has caused some loss of adhesion between the glass fibres and the unsaturated polyester resin, as shown by the smooth regions of the fibre where little resin adheres after fracture...

The selected packaging, the Excel bag, is shown in Figure 7.1. The Excel material is a polypropylene (PP)-based multilayer film, including a polyester ether outer layer and a styrene-ethylene-butylene-styrene (SEBS) tie layer. A natural rubber (NR) stopper is present at the port system of the Excel bag.

Hafeman et al. (2010) obtained a PUR network using hexamethylene diisocyanate trimer and a polyester-ether-based macrodiol containing poly(E-caprolactone), gly-colyde, and D,L-lactide. Their system was able to sustain the release of tobramycin over an extended period of time (up to 2 weeks) with a burst release ranging from 45% to 95%, depending on the glycolide content in the macrodiol. 

On this basis one would predict the formation of a polyester-ether containing both head-to-tall and head-to-head units. This fact was verified by the synthesis of the head-to-tall pol3imer by a direct transesterIfIcatlon procedure ...
