Multifunktionelle Polyether basierend auf Glycidol und aliphatischen Epoxiden
… oxide backbone. The basic monomer is glycidol and its protected derivatives. Protected glycidols such as allyl glycidyl ether, tert.butyl glycidyl ether and especially ethoxyethyl glycidyl ether give linear polymers which can me modified chemically in a second step. The first area of …

Synthesis and characterization of stimuli-responsive microgels based on poly(glycidol)block copolymers
… to ATRP polymerization Cl-terminated poly(glycidol) macroinitiators were prepared by modification of (Omega)-hydroxyl group of poly(glycidol acetal) using 2-chloropropionyl chloride fallowed by selective acidic deprotection of acetal groups. The obtained macroinitiators of different molar …

Preparation of green non-ionic surfactants from 2,3-epoxy-1-propanol
… products in the market. In this work, glycidol has been used as a starting material to produce non-ionic surfactants. Glycidol can be produced from glycerol carbonate, an important chemical intermediate which is synthesised via transesterification from glycerol, a by-product of …

Synthesis and characterization of polymacromonomers based on polyethers
… were used: 1-ethoxyethyl glycidyl ether (glycidol acetal), which after hydrolysis forms hydrophilic glycidol blocks and glycidyl phenyl ether forming hydrophobic blocks. Polymerizable double bonds were introduced by terminating the living chain with p-(chloromethyl)styrene. However, …

Hyperbranched polyglycerol surfactants: a modular approach
… initiated ring opening polymerization of glycidol yielding single tailed HPG surfactants. These surfactants all exhibited high salt stability and elevated cloud points. They exhibited a wide range of surface tensions at 1 wt. % surfactant in water that increased with increasing hydrophobe …

Amphiphilic hyperbranched polyglycerols for industrial and biomedical applications
… multi-branching polymerization (ROMBP) of glycidol using resorcin[4]arene cavitand. The resorcin[4]arene, a cyclic macrocycle of resorcinol, has eight phenolic hydroxyls on one side and four aliphatic “feet” in the opposite side, providing a hydrophobic base for HPG-R. Using HPG-R as an …

Reactive amphiphilic block copolymers for the preparation of hybrid inorganic/organic materials
… synthesis of well-defined polystyrene-block-polyglycidol (PS-b-PG) block copolymers, their micelle formation and the use of these micelles for the preparation of hybrid inorganic/organic materials are described. The hybrid materials are used for patterning of highly ordered titanium dioxide …

Interactions of human primary immune cells with nanoparticles, two-dimensional micropatterns, hydrogels and three-dimensional nanofibres
… endgroups, RGD and GLF as well as six-armed glycidol on the attachment and response of macrophages were investigated. It was found that Star PEG led to the formation of macrophage cell clusters for up to three days of culture. After this period, the cells formed a dense monolayer. Noticeable, …

"Smart" Hydrogels based on Trishydrophilic Triblock Terpolymers
… block copolymers, containing ethylene oxide and glycidol derivatives, was developed. The crucial aspect of this procedure, based on sequential anionic polymerization, was the utilization of the phosphazene base t-BuP4, enabling the anionic polymerization of epoxide monomers in the presence of …
