  1. 1. Photocuring of multifunctional monomers initiated by camphorquinone / amine systems for application in dental restorative resins

    Författare :Nie Jun; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Photocuring; Dental restorative resins; Photoinitiator system: Cainphorquinone amines; Monomers: Meth acrylates; Photoinitiated polymerization kinetics;

    Sammanfattning : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).

  3. 2. Polyhydroxyl and Polyphosphorylcholine functionalized Silica for Hydrophilic interaction liquid Chromatography- Synthesis, characterization and application

    Författare :Nhat Thi Hong Bui; Knut Irgum; Michael Lämmerhofer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrophilic Interaction Chromatography; HILIC; silica; TRIS; acrylamide acrylate; ATRP; iniferter; “controlled living’’ radical polymerization; N; N′-methylenebisacrylamide; MPC; stationary phase; analytisk kemi; Analytical Chemistry;

    Sammanfattning : This thesis focuses on the development of new stationary phases for use in hydrophilic interaction liquid chromatography using TRIS-based and phosphorylcholine typed monomers and porous silica particles as starting substrates. In this thesis, several ways of polymerizing highly hydrophilic mono­mers onto pore surfaces of silica supports are described, based on several “grafting from” schemes. LÄS MER
