RUBBER CHEMISTRY MATADOR RUBBER Summary Rubbers - elastomers - are polymeric materials characterised by their ability of reversible deformation due to external deforming forces. Their deformation rate depends on the structure and molar mass of the deformed RUBBER and on external conditions of the deformation. This characteristics, referred to as elastic and/or hyper elastic deformation, is entropic in nature and results from the ability of RUBBER macromolecules to form a more organised state under influence of deforming forces without deformation of chemical bonds between atoms of the polymer chain or without deformation of their valence angles.
butadiene, synthetic isoprene rubbers, natural rubber); • special - in addition to the basic elastic properties they have at least one special feature, such as resistance to aging, resistance to chemicals, resistance to budding in non-polar oils, resistance to high/low temperatures etc. They are usually manufactured and consumed in lower
