Synthetic Rubber - Lab Report ExampleDuring polymerization the recur bonds of the isoprene monomers give way to single bonds which will lead to further increase in length of intersection point chain. Butyl synthetic rubber-also known as polyisobutylene (C4H8)-is a synthetic rubber and is produced by polymerization of roughly 98% of isobutylene with about 2% of isoprene (Wikipedia, 2006) using BF3, H2O, CH2CL2 as reaction activators under -78C temperature. e.gSimilarities and Differencies In both natural and synthetic rubbers production, the monomers tin can be mixed in various desirable proportions to achieve a wider range of physical, mechanical, and chemical properties through with(predicate) the use additive. The formation of natural and synthetic rubbers are three step Free radical eliminations and substitutions reactions. twain Natural and synthetic rubber reactions require protectants against deterioration during the coagulation and drying (CIWMB).2. In its natural form rubber is too soft to be used for any useful purposes.Natural rubbers tends to be sticky and soft at high temperatures while at low temperatures they are brittle and stiff, making them difficult to process. This is due to a high degree of entropy. Therefore, its properties were improved using special processing techniques. During vulcanization, or curing, of rubber, individual polymer molecules are cogitate to other polymer molecules by polysulphide
