The self-organization and dynamics of bottlebrush polymers consisting of poly(2-bromoisobutyryloxyethyl methacrylate) (PBiBEM) backbone and grafted n-butyl acrylate (PBA) chains are studied as a function of the side-chain length by X-ray scattering,

We investigate the linear viscoelastic response of model telechelic linear and star (of varying functionality) polyisoprene melts with different molar masses above the entanglement limit in relation to their structure. We find that these systems self

The effect of nanoscale confinement on the dynamics of a series of poly(n-octadecyl methacrylate)-b-poly(tert-butyl acrylate)-b-poly(n-octadecyl methacrylate) (pODMA-b-ptBA-b-pODMA) triblock copolymers, synthesized through atom transfer radical polym

A series of well-defined poly(methyl methacrylate)-block-poly(butyl acrylate) 3-arm star block copolymers have been synthesized by ATRP. The incorporation of polar hard segment of PMMA was made possible with the aid of halogen exchange technique. Pha

A series of well-defined poly(n-butyl acrylate)-b-polyacrylonitrile (PBA−PAN) triarm star block copolymers have been synthesized by ATRP. The incorporation of very polar hard segment of PAN was made possible with the aid of the halogen-exchange tec

Three recently synthesized epoxy monomers were studied. All the monomers form a nematic phase in temperatures above 80 °C. This paper presents the dielectric response of pure monomers in the frequency range of 10 6 –10 9 Hz as well as its changes

The mutual miscibility of five binary ethylene/norbomene copolymers of the N(x)E(1-x)/N(y)E(1-y) type where x and y represent the norbornene content in the first and second copolymers, respectively (with x/y of 0.36/0.52, 0.36/0.56, 0.36/0.62, 0.46/0

In this work a mechanical model of deformation of two-dimensional spherulites is proposed taking into consideration its two phase structure (amorphous and crystalline phase) as well as the internal radial correlation of orientation of crystalline ele
