Abstract

Demands imposed on floating objects have necessarily resulted in applying polymer as construction material, as well as in protection systems in shipbuilding and maritime affairs. Natural rubber is known as a very important industrial material gained from (Hevea Brasiliensis). It is a polymeric material and by chemical structure it is mostly cis 1.4-polyisoprene, belonging to the group of elastomers and due to its special characteristics it has a wide usage. Familiarity with its structure (especially nanostructure of the gel phase) and with its molecular dynamics is very important in defining mechanical and application characteristics. Natural rubber, as well as synthetic elastomers, must be submitted to the process of cross-linking which causes transversal linking of chain molecules. This process results in desired usage characteristics of the material. The material prepared in this way shows appropriate elasticity, tensile strength, viscosity and resistance to wearing.
