2. Polyphosphazene - Wikipedia

   en.wikipedia.org/wiki/Polyphosphazene

   [2] [3] [4] Of these early species, poly[bis(trifluoroethoxyphosphazene], [NP(OCH 2 CF 3) 2] n, has proved to be the subject of intense research due to its crystallinity, high hydrophobicity, biological compatibility, fire resistance, general radiation stability, and ease of fabrication into films, microfibers and nanofibers.

3. Polytetrahydrofuran - Wikipedia

   en.wikipedia.org/wiki/Polytetrahydrofuran

   Terathane container owned by DuPont (before the business was sold to Invista). The main use of polytetrahydrofuran is to make elastic fibres such as spandex (elastane) for stretchable fabrics [4] and for polyurethane resins.

4. Polyoxymethylene - Wikipedia

   en.wikipedia.org/wiki/Polyoxymethylene

   To make polyoxymethylene homopolymer, anhydrous formaldehyde must be generated. The principal method is by reaction of the aqueous formaldehyde with an alcohol to create a hemiformal, dehydration of the hemiformal/water mixture (either by extraction or vacuum distillation) and release of the formaldehyde by heating the hemiformal.

5. Polyethylene - Wikipedia

   en.wikipedia.org/wiki/Polyethylene

   Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.

6. Polyvinylcarbazole - Wikipedia

   en.wikipedia.org/wiki/Polyvinylcarbazole

   Polyvinylcarbazole was discovered by the chemists Walter Reppe (1892-1969), Ernst Keyssner and Eugen Dorrer and patented by I.G. Farben in the USA in 1937. [4] [1] PVK was the first polymer whose photoconductivity was known.

7. Polypropylene - Wikipedia
