	Self-extinguishing polyester molding compositions - Patent 3947421
		Preferably, the self-extinguishing polybutylene terephthalate moldings are manufactured by mixing granular polybutylene terephthalate with the additives mentioned, subsequently melting and homogenizing the mixture in an extruder, extruding it into a water bath, and granulating and drying it.
		A mixture of 3.5 kg of polybutylene terephthalate granules, 437 g of an adduct of hexachlorocyclopentadiene and cyclooctadiene-1,5, 245 g of antimony trioxide and 262 g of chrysotile containing 40.1% SiO.sub.2 and 40.8% MgO was extruded and used to injection-mold test bars, as described in Example 1.
		A mixture of 3.5 kg of polybutylene terephthalate, relative viscosity = 1.65, 420 g of octabromodphenyl ether, 175 of antimony trioxide and 175 g of chrysotile (composition as in Example 1) was extruded and used to injection-mold test specimens.

	Method and apparatus for making NIBS and ink reservoirs for writing and marking instruments and the resultant products ...
		Melt blown bicomponent fibers comprising a sheath of polyethylene terephthalate or a copolymer thereof and a core of nylon 6,6 and a reservoir or a nib in a writing or marking instrument comprising a porous element formed from such fibers bonded to each other at spaced points of contact.
		As defined in the '766 patent, the term "polyethylene terephthalate or a copolymer thereof" refers to a homopolymer of polyethylene terephthalate or a copolymer thereof having a melting point which is higher than the melting point of the thermoplastic core material in the bicomponent fiber.
		It is believed that polyethylene terephthalate and its copolymer of a broad range of intrinsic viscosities are useful according to this invention, although those with lower intrinsic viscosities are preferred.

	SRI Consulting CEH Report
		Polybutylene terephthalate (PBT) resins and polyethylene terephthalate (PET) engineering resins are high-performance, high-molecular-weight materials that can be converted into functional components and parts that are in turn used in a diversified array of assemblies for automotive, electrical/electronic, appliance and industrial equipment applications.
		In mid-2006, DuPont announced that it was going to make polytrimethylene terephthalate (PTT) engineering thermoplastic from terephthalic acid (TPA) and propanediol (bio-PDO), which in turn is made from renewable resources.
		The level of raw material 1,4-butanediol (BDO) required is less than with standard PBT production; thus emissions of CO and consumption of oil are reduced, as well as disposal of postconsumer PET bottles in landfills.
