Group transfer polymerization in bulk methacrylates

Abstract Group transfer polymerization (GTP) is a method developed to obtain targeted (meth)acrylic polymers in solution at ambient temperatures. In this work, it employed with methacrylic monomers low Ð bulk. regard, different initiator systems that exhibit mechanisms are compared concerning the molecular weight, polydispersity and double bond conversion of resulting bulk polymers. The respective were chosen carefully give broad overview earlier initiator‐catalyst combinations 1‐methoxy‐1‐(trimethylsiloxy)‐2‐methylprop‐1‐ene (MTS) & tetrabutylammonium cyanide (TBACN) more recently investigated initiating MTS trityl tetrakis (pentafluorophenyl)borate (TTPB) or dimethyl phenyl silane (DMPS) tris (BCF). described applied as two‐component (2K) system ensure homogeneous distribution catalyst monomer. addition 2K experiments, photochemical initiation also formulations. Therefore, photoacid generator (PAG) used trigger reaction by irradiation UV light. A highly controlled photopolymerization was way achieving polymer high conversion.
