National Association for PET

NAPCOR, National Association for PET Container Resources, [http //www.napcor.com/learn], March 2001. 

National Association for PET Container Resources (NAPCOR) Facilitates the economical recovery of plastic containers, with an emphasis on PET, including U.S. recycling industry statistics and member company profiles, http //www.napcor.com National Association of Corrosion Engineers (NACE) International (corrosion) http //www. nace.org... 

The gross recycling rate of PET bottles was 29.3% in the United States for 2011 (National Association for PET Container Resources (NAPCOR) 2013). In California, the recycling rate of PET bottles is greater than 60% (CalRecycle PET 2013). 

The National Association for PET Container Resources (NAPCOR) [115] is the trade association for the PET plastic industry in the United States and Canada. Their activities, along with those of the Association of Post-consumer Plastic Recyclers (APR) [116], promote recycling ideals in the packaging and bottle industries. 

Preparation of mono-adducts of fullerene - for studies on electrostatic interactions - was undertaken by cyclopropanation of fullerene with appropriately functionalised malonic esters 1 (Bingel reaction) to form 2. Coupling with the tert-butyl protected oligoamide-amino-dendron 3 and subsequent hydrolysis lead to the water-soluble fullerene dendron 5, which can carry up to nine negative charges after depro to nation. After association with the zinc complex of cytochrome C, photoinduced electron transfer (PET) from the redox protein to the fullerene can be accomplished, which was studied by fluorescence spectroscopy. 

Whinfield and W. Dickson, working at the Calico Printers Association (2,3). Other polymers pioneered by these workers included poly(l,3-propylene terephthalate), 3GT, poly(l,4-butylene terephthalate), 4GT, and the polyester from ethylene glycol and l,2-6is(4-carbox5 henoxy)ethane, known as CPE-2G or Fiber-0 (4). Of these materials, PET was selected for development as a melt-spinnable synthetic fiber, but commercialization was impossible until after the end of World War II. Eventually, when the various national economies were back on a peacetime footing, PET polymer and fibers derived from it were put into production. The whole market-driving force for polyester at this time was in the form of synthetic fibers. In the United Kingdom, the new material was manufactured by Imperial Chemical Industries Ltd. imder the trade name Terylene, while DuPont introduced it to the United States in 1953 as Dacron (see Polyesters, Fibers).
