Lamellar Structure in Melt Crystallized Low Density Polyethylene. 2. Study of the Crystalline Phase after Chlorosulfonation

A combined X-ray diffraction and DSC investigation of the crystalline phase in lamellar low density polyethylene after conventional chlorosulfonation treatment has been carried out. Our results indicate that the acid attack does not involve any heavy group penetration within the lattice. The locatio...
