CRYSTALLIZATION KINETICS AND MORPHOLOGY OF OLEFIN BLOCK COPOLYMER (OBC)/SILICA COMPOSITES
The novel chain shuttling polymerization technology developed by The Dow Chemical Company1, allows for continuous synthesis of olefin block copolymers (OBCs) with tunable properties. The OBCs consist of crystallizable ethylene-octene blocks with low comonomer content and high melting temperature (hard segments), alternating with amorphous blocks with high comonomer content and low glass transition temperature (soft segments)~2. Compared to a random ethylene-octene copolymer, the OBC has a higher melting temperature and a well organized crystalline morphology. Additionally, OBCs can provide sufficiently high interfacial adhesion between PP and HDPE3 and maintain excellent elastomeric properties at temperatures far higher than traditional ethylene based elastomers, allowing them to be used for high temperature applications.
