We are living in the “Materials World”. We consume more polymeric materials than all other types of synthetic materials combined. Polymers are chain molecules and their materials properties are determined to a large extent by chain microstructure and orientation. Synthesis of novel polymeric materials with tailor-made properties provides a great challenge to polymer scientists and engineers. Presented are several research examples that include high-strength polyethylene fibers made by nano-extrusion polymerization; long chain branched polyethylene that offers good combination of melt strength and processability; hyperbranched polyethylene having high-molecular weight but low viscosity for printing; nano-patterning through self-assembly of polymer grafts, and semi-batch reactor technology for controlled gradient copolymers. Presented is a chemical engineer’s point of view on advanced polymer materials.
