The fisheyes in the blown film of a metallocene linear low density polyethylene (mLLDPE) were isolated by the dissolution method,and the solubility,the molecular weight,and the crystallinity of the separated parts were characterized by gel permeation chromatography (GPC) and differential scanning calorimetry (DSC).The results show that the fisheyes are composed of (92.6±1.1)% of soluble mLLDPE and (7.4±1.1)% of insoluble,slightly crosslinked high density polyethylene gel.
