What is the chemical formula for rubber?

Answer 1

The chemical formula for natural rubber is (CH2CHC(CH3)CH2)n this is a polymer often call cis-polyisoprene. Structurally each unit in the polymer contains a double bond. This makes the rubber reactive as it is an unsaturated polymeric hydrocarbon.

Rubber as met in everyday life is a complex mixture of polymeric substances which may include natural rubber in the manufacturing process. Rubber based on natural rubber is generally vulcanised with sulfur or sulfur compounds to join the chains together by sulfur cross links. Many additives are included to change the characteristics of the rubber product, these include fillers such as carbon black, or plasticisers.

Artificial rubbers include neoprene, polychloroprene.

Answer 2

There are a number of types so it is difficult to give the formula. All are polymers as is natural rubber.

Answer 3

rubber is a general name for a variety of different material. They are recognized by their flexible structure and sometimes sticky surface. But there is no formula, mostly used rubber is already a mixture of different compounds, mostly hydrocarbons.

Answer 4

The chemical formula for natural rubber is (C5H8)n, where n represents a variable number of repeating units. Synthetic rubber can have different chemical formulas depending on the specific type of rubber being referenced.

Answer 5

-(CH2-C=CH-CH2)-n
