WebIsocyanate Reactions. Process Analytical Technology for Continuous Measurement of NCO. Isocyanates are critical building blocks for high performance polyurethane-based polymers that make up coatings, foams, adhesives, elastomers, and insulation. Concerns over exposure to residual isocyanates led to new limits for residual isocyanates in new ... WebMany attempts to mimic the structure of biopolymers via precision polymer synthesis with reversible deactivation radical polymerization (RDRP) techniques have been made. For peptides and proteins and their building blocks in particular, a broad variety of mimics have previously been suggested.
