U.S. Pat. No. 3,830,274 (Waser) discloses an elastomer blend and a pneumatic tire sidewall prepared therefrom which comprises 20-60% weight percent of either natural or synthetic cis-1,4-polyisoprene compounded with 20-35 weight percent of an EPDM polymer and with from 20-45 weight percent of bromobutyl rubber having specific characteristics.
Vulcanization & Accelerators Nocil
An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanizationand thus improving 'aged'

Types of Polymerization: Condensation vs. Addition,
The end groups remain reactive through the entire process. Addition polymerization results in homo-chain polymers whereas condensation polymerization results in hetro-chain polymers. The most significant difference is that in addition polymers there is no loss of atom. But in condensation reaction, there is a loss of a molecule of water
Buna rubber: Buna rubber is a synthetic rubber prepared by polymerization of butadiene in the presence of sodium metal as catalyst. There are two types of Buna rubber- Buna-N and Buna-S. Buna-N: This rubber is prepared by the co-polymerisation of butadiene and acrylonitrile in the presence of sodium metal. The structure of Buna-N is shown below.
Chloroprene Rubber an overview ScienceDirect Topics
Chloroprene rubber (CR) is a synthetic rubber that is also known by the trade name Neoprene. CR has a good balance of properties, including good chemical stability and usefulness over a wide temperature range. Examples of the uniaxial compressive response are summarized in Figures 11.6 and 11.7.The rubber material was tested at four different strain rates in uniaxial
