Plastic Monomers

Plastic is produced from plastic raw material, usually this material called as monomer in general chemistry. Monomer than be converted into polimer that have plastic properties. Many kind of monomers used as plastic material, for example is Phenol.
Phenol has been made, over the years by a variety of processes. Many companies producing it and use it internally and do not sell it on the open market. The principle in use in the United States is the peroxidation of cumene (isopropyl benzene). The conversion of cumene to cumene hydroperoxide given a 25 to 50 % yield per pass. The cumene hydroperoxide, which has the dangerous explosive properties of other hydroperoxides, decomposes into acetone and phenol in the presence of sulfuric acid. The by-product of acetone dominates the acetone market. Phenol also can be prepared from toluene, and one small plant in the United States produce it this way. This process is more widely used in Europe.

The below is the abreviation of many plastic monomers:
  1. CA: Cellulose Acetate
  2. CPVC: Chlorinated Polyvinyl Chloride
  3. MF: Melamine Formaldehyde Resin
  4. NBR: Poly (acrilonitrile-co-butadiene)
  5. PAN: Polyacrilonitrile
  6. PC: Bisphenol A Polycarbonate
  7. PE: Polyethylene
  8. PETP: Poly (ethylene Terephtalate)
  9. PF: Phenol Formaldehyde Resin
  10. PIB: Polyisobutylene
  11. PMMA: Poly (methacrylate)
  12. POM: Polyoxymethylene
  13. PP: Polyprophylene
  14. PTFE: Polytetrafluoroethylene
  15. PUR: Polyurethane
  16. PVAC: Poly (vinyl Acetate)
  17. PVAL: Poly (vinyl Alcohol)
  18. PVB: Poly (vinyl butyral)
  19. PVC: Poly (vinyl chloride)
  20. PVDC: Poly (vinylidene chloride)
  21. PVDF: Poly (vinylidene Fluoride)
  22. PVF: Poly (vinyl pyrrolidone)
  23. UF: Urea-Formaldehyde Resin
