How do you write the formula of a polymer?

Answer 1

--(-CH2 - CH(CH3)-)-- n

This is polypropylene.

polystyrene is the same except the (CH3) is replaced by a phenyl group

--(-CH2 - CH(C6H5)-)--n

PVC (polyvinyl chloride

--(-CH2 - CH(Cl)-)-- n

The 'n' represents any number(n) of monomer units. Maybe thousands or millions.

Answer 2

polymerisation is a process in which many monomer molecules react and join together to give a polymer which requires high pressure and a calyst, the reaction involves unsaturated monomers like alkenes (eg. ethene) for which the formula is CnH2n

Answer 3

They are sometimes represented by the formula Cx(H2O)y where x is usually a large number between 200 and 2500. Also, considering that the repeating units in the polymer backbone are often six-carbon monosaccharides, the general formula can also be represented as (C6H10O5)n where 40≤n≤3000. This is the more common one.

Answer 4

Those are two general terms, so there is no chemical formula. A polypeptide is for instance a polymer where it consists of amino acids (monomer). Same with polyester which consists of esters (monomer).

Being more specific, ethylene has the formula CH2=CH2 and when polymerized into a polymer would be (--CH2-CH2--)N where N is a very large number. The same principle applies to many monomers and polymers.

Answer 5

It is represented with vacant valencies of two atoms of basic unit (monomer) as

(-CH2-CH2-)n for polythene and (-CH2-CH2-O-)n for poly ether, n= a large whole no.

Answer 6

the formula of a compound is H2O2
