The attachment to rat Kupffer cells of polymeric microspheres, sterically stabilized with different amounts of pendant poly(ethylene oxide) (PEO), was assessed in vitro. Four types of copolymer polystyrene (PS) microspheres were synthesized by variation of four possible monomer ratios that

A new strategy for the preparation of substituted imidazolidin-2-ones in two steps from readily available N-allylamines is described. Addition of the amine starting materials to isocyanates affords N-allylureas, which are converted to imidazolidin-2-one products with generation of two bonds and

On lithiation with lithium amides, N-allyl-N'-aryl ureas undergo rearrangement with transfer of the aryl ring from N to the allylic α carbon. From the α-arylated products, a further aryl transfer under the influence of a chiral lithium amide allows the

The chemical changes induced by electron-beam irradiation of mixtures of N-allylurea (AU) and amorphized starch were studied by spectroscopic methods for identifying and monitoring the reactions providing the blend with stabilized physical properties. Spectral modifications essentially concerned the AU constituent

There are few examples of polymers that exhibit upper critical solution temperature (UCST) behavior under physiological conditions of temperature, pH, and ionic strength. In this study, we demonstrated that polymers with ureido groups undergo UCST-type phase transitions under physiologically relevant
