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.

Difference between organic and inorganic polymers.

Difference between organic and inorganic polymers. Definition Organic polymers are the polymers that essentially contain carbon atom in the backbone. Inorganic polymers are the polymers that have no carbon atom in the backbone. Structure Most organic polymers have simple structures. Almost all inorganic polymers are highly branched and have complex structures. Electrical Conductivity In most of the aqueous solutions, organic polymers are typically poor conductors of electricity and heat. Inorganic polymers in aqueous solutions are good conductors of electricity, this is because they have high ability to ionise and this makes them better conductors. Flammability Organic polymers are flammable whereas inorganic polymers are nonflammable. Effect on nature Organic polymers are environmental friendly as these are biodegradable. Inorganic polymers are not environmental friendly as these are non biodegradable. Examples Organic polymers include polysaccharide...
