Question

give chemical equation for preparing polythene (polymerization).

first would be the brainliest!!!​

Answer 1

Explanation:

An example of the first type of reaction is the union of thousands of ethylene molecules that gives polyethylene.

nH2C=CH2 → [―CH2CH2―]n

Other addition polymers include polypropylene (made by polymerizing H2C=CHCH3), polystyrene (from H2C=CH C6H5), and polyvinyl chloride (from H2C=CHCl).

Answer 2

Explanation:

Chemical formula =(C2H4 )n

Melting point =115 -135°c ( 239-275°F 388-408K)

Density = 0.88-0.96 g /cm3

CAS Number =9002-88-4.
