Enzymatic synthesis of polymers containing nicotinamide mononucleotide.
Nicotinamide mononucleoside 5'-diphosphate in its reduced form is an excellent substrate for polynucleotide phosphorylase from Micrococcus luteus both in de novo polymerization reactions and in primer extension reactions. The oxidized form of the diphosphate is a much less efficient substrate; it can be used to extend primers but does not oligomerize in the absence of a primer. The cyanide addu...
متن کاملSynthesis of (Bio)degradable Polymers via Thiol-ene Click Polymerization
Towards the development of (bio)degradable polymers with medical relevance a non-radical thiolene synthesis route is investigated. In this work, step growth polymerization based on Michael addition click reactions is presented. Homotelechelic RAFT polymers were conjugated leading to polymers with molar weight distribution typical for a step growth polymerization, tailing up to 100 000 g∙mol-1 i...
متن کاملPolymerization of Thin Film Polymers
Polymeric coatings such as polyurethanes, acrylic, epoxies and silicones have been used for over 40 years to protect printed wiring boards (PWB) from moisture, handling and environmental influences. Special semiconductor grade polymers have been developed for chip passivation layers. Polyimide became the standard passivation layer for memory chips and other devices needing surface protection fo...
متن کاملSolution-phase synthesis of 1D tubular polymers via preorganization-polymerization.
The synthesis of one-dimensional tubular polymers via a preorganization-polymerization approach is presented. Prior to polymerization, photo-reactive monomers self-assemble into one-dimensional tubular structures in aqueous medium. The supramolecular polymers are subsequently converted into covalent polymers by light-induced anthracene dimerization.
متن کاملHydrophilic Natural Polymers for Sustained-controlled Release of Calcium Hydroxide
Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH chan...
