Synthesis and Photopolymerization of Novel Dimethacrylates
… kinetics of ethoxylated and propoxylated dimethacrylates was investigated by isothermal DSC. The DSC curves showed a rapid increase in rate due to the Trommsdorff effect, and then a decline due to the decrease of monomer concentration and the autodeceleration effect. The monomers with …

Novel Carbazole Based Methacrylates, Acrylates, and Dimethacrylates to Produce High Refractive Index Polymers
… aromatic based methacrylates, acrylates, and dimethacrylates are excellent materials with many applications in dentistry, microelectronics, and optics, including optical eye wear, fiber optics, and non-linear optics, such as holography. Carbazole based polymers have demonstrated good optical, …

Inter-Relationships Between Chemistry, Network Structure and Properties of Chain Growth Dimethacrylate Thermosets
… compared to oligomeric structures containing dimethacrylates derived from epoxy terminated oligomers (from bisphenol-A and epichlorohydrin). Both types of dimethacrylates co-cured with methyl methacrylate exhibited increases in Mc and fracture toughness as the concentration of methyl …

Bioabbaubare Polymernetzwerk-Systeme mit Formgedächtniseffekt und kristallisierbarem Schaltsegment
… of oligo(Epsilon -hydroxycaproate-ran-glycolate)dimethacrylates. By variation of the glycalate content the shape memory transition temperature can be adjusted between 27°C and 49°C. By polymerization of the macromonomers in the presence of butyl acrylate, AB-crosslinked materials are obtained. …
