The amount of high molecular weight hindered amine light stabilizer (HALS) in low density polyethylene (LDPE) was determined using two pretrement methods; Soxhlet extraction and pressurized solvent extraction (PSE). The recoveries of high molecular weight HALS obtained by the two methods were compared.
