Butyl rubber.

Butyl rubber;

  • Butyl rubber, sometimes just called "butyl" is a synthetic rubber, a copolymer of isobutylene with isoprene.
  • It is also known as IIR. The abbreviation IIR stands for isobutylene isoprene rubber.
  • Butyl rubber is produced by polymerisation of about 98% of isobutylene with about 2% of isoprene.
    This image shows synthesis of Butyl rubber from isobutylene and isoprene.

  • Butyl rubber (an elastomer) is impermeable to air.
  • Butyl rubber has good resistance to aging and weathering.
  • Butyl rubber has good resistance to chemicals and ozone.
  • Butyl rubber is used in the manufacture of adhesives.
  • It is also used in lubricants and chewing gums.
  • The first major application of butyl rubber was tire inner tubes.
  • Butyl rubber is used in the manufacture of agricultural chemicals.

Determination of molecular weight by osmotic pressure method

Determination of molecular weight by osmotic pressure method. Osmotic pressure method is also called membrane osmometry. This method is widely used to determine the number average molecular weight of polymers. This method is based on the phenomenon of osmosis. If a pure solvent is separated from a solution through a semipermeable membrane, due to concentration (chemical potential) difference between the solvent and solution, the solvent will flow into the solution through semipermeable membrane. The pressure applied on the solution to completely stop the flow of solvent into it through semipermeable membrane is called osmotic pressure. The theory of osmotic pressure also applies to a solution of polymers. Ordinary solution obeys Van't Hoff equation i.e π=cRT/M Where π is osmotic pressure, c  is concentration in mass per unit volume, R is gas constant, T is temperature and M is molar mass. The polymer solution are non ideal. Taking into account their deviation and us...

Polypropylene (PP)

Polypropylene (PP). Polypropylene (PP) is also known as polypropene. Polypropylene is made from the polymerisation of propylene gas in the presence of Zeiglar Natta catalyst or metallocene catalyst. Polypropylene. Thus propene (or propylene) is the monomer of polypropylene. Polypropylene is a highly flammable material. It is sensitive to microbial attacks, such as bacteria and mold. It exhibits excellent resistance to diluted and concentrated acids, alcohols and bases. Polypropylene is used to make lunch boxes, margarine containers, yogurt pots, syrup bottles etc. Disposable syringes is the most common medical application of polypropylene. Polypropylene rope and twine are very strong and moisture resistant very suitable for marine applications. Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats. Uses of Polypropylene. Questions on polypropylene; Q1) What is polypropylene? Ans) Polypropylene is a polymer of propylen...
