Rubber nanocomposites with nanocellulose - Free Download
To overcome the difficulty of obtaining a homogeneous dispersion by the incorporation of nanocellulose into the elastomer compound, we carried out the mixing process in liquid phase: the fibrous material was reduced to a viscous, alkaline aqueous solution of sodium cellulose xanthate, while the elastomer was used as an acid-sensitive aqueous rubber emulsion.

Natural rubber
Natural rubber, also called India rubber or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Malaysia and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers.

Adhesive
Natural rubber and polychloroprene (Neoprene) are commonly used contact adhesives. Both of these elastomers undergo strain crystallization . Contact adhesives must be applied to both surfaces and allowed some time to dry before the two surfaces are pushed together.

In the 1930s, Germany developed the emulsion copolymerisation of butadiene-styrene (Buna S), whereas sodium polybutadiene continued as the principal general purpose synthetic rubber in the Soviet Union. The advent of World War II highlighted the importance of rubber as a raw material.
