Question

The difference in the densities of low density (LDP) and high density polymers (HDP) is due to the fact that (A) LDP are highly branched structures while HDP consists of closely packed linear molecules (B) LDP are linear chains while HDP are branched chains of polythene (C) both LDP and HDP are unbranched linear chains with different lengths (D) at high temperature, the density of polymer is reduce

Tardigrade Admin · Accepted Answer

LDP obtained through the free radical addition and H-atom abstraction has highly branched structure. Due to this branching, the density of LDP becomes low. Whereas HDP is obtained when addition polymerisation of ethene takes place in a hydrocarbon solvent in the presence of a catalyst such as triethylaluminium and titanium tetrachloride. It consists of linear molecules and has a high density due to close packing.

Q. The difference in the densities of low density $(L D P)$ and high density polymers $(HD P)$ is due to the fact that

$L D P$ are highly branched structures while $HD P$ consists of closely packed linear molecules

$L D P$ are linear chains while $HD P$ are branched chains of polythene

both $L D P$ and $HD P$ are unbranched linear chains with different lengths

at high temperature, the density of polymer is reduce
