I am in need of etching polyisobutylene from the blend of low-density
polyethylene and polyisobutylene. I tried with tetrahydrofuran which is
solvent only for polyisobutylene but it is not successful. So suggest
me a method for etching

Blend is a blend so you cannot extract one without affecting the other.
PE is pretty poorly soluble. All that you will achieve is a swelling
of the mix and resulting change in shape of your material. Try some
mechanic procedure, like abrasive or a frikkin laser!
