Cocrystallization and Phase Segregation of Polyethylene Blends between the D and H Species.4.The Crystallization Behavior As Viewed from the Infrared Spectral Changes

摘要: Through detailed analysis of the temperature dependence IR spectra, structural change occurring in cocrystallization and phase segregation processes has been investigated for polyethylene (PE) blends between deuterated hydrogeneous species with various degrees branching. In blend high-density PE (DHDPE) linear low-density (LLDPE(2), 17 ethyl branches/1000 carbons), almost perfect occurs, during which D H chains are distributed statistically randomly crystalline lamellae at a probability determined by relative content
