Ion containing copolymers via the emulsion copolymerization of polar and ionic vinyl monomers
… copolymers by emulsion copolymerization of polar vinyl monomers with ionic vinyl monomers has been studied. The copolymerization of n-butyl acrylate with sodium-pstyrene sulfonate proved to be particularly rapid. With the proper choice of chain transfer agent soluble polymers with enhanced rubbery …

Polymerisation of vinyl monomers in continuous-flow reactors. An experimental study, which includes digital computer modelling, of the homopolymerisation of styrene and methylmethacrylate by anionic and free radical mechanisms respectively in continuous flow-stirred-tank reactors.
An introduction is given to the background theory and scientific literature of the major subject areas of interest in this thesis, namely the chemistry of free radical and anionic polymerisation, molecular weight control in each type of polymerisation, polymerisation reactors, computer simulation …

Initiated chemical vapor deposition of fluoropolymer coatings for the surface modification of complex geometries
… has been used to polymerize a wide variety of vinyl monomers such as glycidyl methacrylate (adhesive) and 2-hydroxyethyl methacrylate (hydrophilic). The proposed polymerization mechanism is the classical free radical polymerization mechanism of vinyl monomers. Monomer and initiator gases are …

Initiated chemical vapor deposition of functional polyacrylic thin films
… initiator, while retaining functional groups of monomers, which has been confirmed in the infrared spectroscopy, nuclear magnetic resonance, and x-ray photoelectron spectroscopy of iCVD poly(glycidyl methacrylate) (PGMA) thin films. Studies of PGMA iCVD deposition kinetics and molecular weights …

Multi-stage polymer systems for the autonomic regeneration of large damage volumes
… The versatile gelation chemistry gels over 20 vinyl monomers to yield both thermoplastic and thermosetting polymers. The healing efficacy of the two-stage system was studied in thin, vascularized epoxy sheets. By splitting the chemistry into two low viscosity fluids, we demonstrated …

Group 10 Metal Catalytic Olefin Polymerization and Synthesis of Ethylene/Acrylate Block Copolymers
… were able to copolymerize ethylene with polar vinyl monomers or α-olefins with high incorporation. Lastly, the ethylene/acrylate block copolymers were successfully synthesized by the iminopyridyl Ni complexes via photo-induced radical polymerization. The development of cheaper and less toxic Ni …

Synthesis and evaluation of quadruple hydrogen-bonding modules for smart materials applications
… the synthesis of DAN and DeUG units featuring vinyl monomers, azide, alkyne, and other reactive groups for various coupling chemistries. Evaluation of the DAN and DeUG pair as a coupling agent for improving the interfacial adhesion between styrene and glass is explored in chapter four. …

Correlation of physical and chemical properties of anhydride-cured epoxy resins with theoretical structure
… the lowest property retentions due to crazing. Vinyl monomers were added to the unsaturated systems in an attempt to enhance properties by promotion of the reaction through unsaturation. These additions were found to produce no advantageous properties except viscosity reduction; an exception …

Weak polyacid brushes : synthesis, swelling behavior, complex formation and micropatterning
… surface-initiated free radical polymerization of vinyl monomers was triggered by thermal cleavage of the initiator ("grafting from" polymerization). By varying the monomer concentration and the polymerization time, the molecular weight of the surface-attached polymer chains and the anchoring …
