In 1999 Shell introduced their Corterra polymers, polyesters made from 1,3-propanediol and terephthalic acid. This polymer, PTT (polytrimethylene terephthalate), was first synthesized in 1941, saw a long ges-... 

Together with purified terephthalic acid, 1,3-propanediol is used to produce polytrimethylene terephthalate (PTT), a polymer with remarkable "stretch-recovery" properties. The desirable attributes of PTT have been known since the 1940s, but high production costs prevented its entrance into the polymer market (29). In the 1990s, a new fossil-based route to 1,3-propanediol was developed enabling the production of PTT for higher-value applications, and PTT polymers were introduced into the market by DuPont and Shell Chemicals (29,30).

Other Uses of Ethylene Oxide. About 2 percent of ethylene oxide is consumed in miscellaneous applications, such as its use as a raw material in manufacture of choline, ethylene chlorohydrin, hydroxyethyl starch, and hydrox-yethyl cellulose and its direct use as a fumigant/ sterilant. Production of 1,3-propanediol via hydroformylation of ethylene oxide was begun on a commercial scale in 1999. 1,3-Propanediol is a raw material for polytrimethylene terephthalate, which finds uses in fibers, injection molding, and in film. Use of ethylene oxide in making 1,3-propanediol is expected to be as much as 185 million lb by 2004, up from 12 million lb in 1999. 

Polytrimethylene Terephthalate Fiber A synthetic fiber noted for its dyeability and colorfastness, used mostly in carpets. 

A method of re-cycling polytrimethylene terephthalate containing up to 0.5 wt% acrolein by depolymerizing at 210°C for 60 minutes to re-generate 1,3-propanediol and terephthalic acid was developed by Kato [6]. In this process the conversion was 100%. 

Nonolefinic thermoplastic polymers that in principle may be blended with polyolefins include polyamides (nylons) such as polyamide 6, polyamide 66, polyphenylene sulfide (PPS), polyphenylene ether (PPF), and polyphenylene oxide (PPO) polyesters such as polyethylene terephthalate (PET), polybutylene terephtha-late (PBT), polyethylene naphthalate (PEN), polytrimethylene terephthalate (PTT), polycarbonates, polyethers, and polyurethanes vinyl polymers such as polystyrene (PS), polyvinyl chloride (PVC), polymethylmethacrylate (PMMA), and ethylene... 

Another of the pioneer polyesters was polytrimethylene terephthalate (PTT). This was recognized very early on as a fiber with outstanding resilience. PTT has been known in many ways as an ideal textile fiber for over 60 years. It remained on the shelf until, in the last decade, it became a commercial product owing to two new routes to the crucial intermediate 1,3-propanediol. One route is petrochemically derived (hydroformylation of ethylene oxide), while the other is a fermentation route using corn sugar to make 1,3-propanediol directly using genetically modified bacteria [40]. 

The core-sheath (c-s) configuration is adaptable because many different polymers may be applied as a sheath over a solid polyester core, thus giving a variety of modified surface properties while maintaining all the major fiber and textile properties of PET. An early patent by Shima and coworkers uses an eccentric core-sheath configuration to achieve spiral crimp in a yarn [67]. A recent patent by Chang and coworkers discloses the use of side-side or eccentric c-s bicomponent fibers to achieve a self-crimping yarn made from polytrimethylene terephthalate, where one component is a melt-blend of PTT with a small amount of polystyrene [68].
