In order to improve the quality of LLDPE, a comonomer is generally selected and added for the modification of strength.

It is general practice to copolymerize PE with a comonomer having high molecula weight to improve mechanical strength. As the molecular weight of the comonomer becomes higher, the strength of PE goes up.
