2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Na 2 (OC 6 H 4) 2 CMe 2 + COCl 2 → 1/n [OC(OC 6 H 4) 2 CMe 2] n + 2 NaCl. In this way, approximately one billion kilograms of polycarbonate is produced annually. Many other diols have been tested in place of bisphenol A, e.g. 1,1-bis(4-hydroxyphenyl)cyclohexane and dihydroxybenzophenone. The cyclohexane is used as a comonomer to suppress ...

5. Closed-cell PVC foamboard - Wikipedia

   en.wikipedia.org/wiki/Closed-cell_PVC_foamboard

   After the war, PVC was not a popular choice of materials in the marine industry due to its density. In the 1970s, the need for a strong, moisture-resistant material led to plastic manufactures working with PVC to make it lighter. This led to the creation of PVC foamboard, by combining PVC with polyurea at the molecular level. [1]

6. Poly(4-vinylphenol) - Wikipedia

   en.wikipedia.org/wiki/Poly(4-vinylphenol)

   Poly(4-vinylphenol), also called polyvinylphenol or PVP, is a plastic structurally similar to polystyrene. It is produced from the monomer 4-vinylphenol, which is also referred to as 4-hydroxystyrene. PVP is used in electronics as a dielectric layer in organic transistors in organic TFT LCD displays.

7. Carbonate ester - Wikipedia

   The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). [ 1 ] Carbonate esters can be divided into three structural classes: acyclic, cyclic, and polymeric.
