Highly polar rubbers GABA 100MG interact with each other through their active functional groups via condensation or substitution reactions at high temperature.Chlorosulphonated polyethylene (CSM) rubber is a highly reactive rubber, the reactivity of with is due to the -SO2CI groups.When CSM reacts with nit rile rubber (NBR), a chemical reaction takes place between the two rubbers at high temperature.

Fourier transform infrared (FTIR) studies support that CSM/NBR (50/50 w/w) isothermally induces a self cross-linking blend, when cross-linking takes place via the acrylonitrile groups of NBR Medical Carts and the SO2CI groups or the insitu generated allyl chloride moieties of CSM.There is a loss of some -CN groups during cross-linking.This may be due to an attack on the -CN groups by HCI (produced during the heating of CSM) in the presence of inherent moisture in the polymers.

Amid type of linkage is formed due to cross-linking.
