Question

what is the structural difference between HDP and LDP? how does the structure account for different behaviour and nature,hence the use of a polymer?

Answer 1

Explanation:

HDP and LDP are high-density polythene and low-density polythene respectively.HDP has a linear structure whereas LDP is highly branched.HDP has high density due to close packing of molecules in it.

HDP and LDP differ in various aspects as given below:

HDP LDP

Chemically inert and tough chemically inert but flexible

Has higher melting point has a lower melting point

Used to make buckets, used to make flexible pipes,

dustbins etc. toys etc.

Answer 2

HDP= HIGH DENSITY POLYTHENE

LDP= LOW DENSITY POLYTHENE
