Two polystyrene-b-poly(ethylene oxide) (PS-b-PEO) diblock copolymers differing in molecular mass (49 and 78 kDa) but possessing the same PEO cylindrical morphology are examined to elucidate their dynamics. Of particular interest here is motion of blocks involved rigid amorphous fraction (RAF). An analysis complementary thermal calorimetry X-ray scattering data confirms presence microphase-separated as well semicrystalline structure each copolymer. Molecular within copolymer systems monitored...
Abstract Morphology and NMR self-diffusion of two miktoarm star copolymers differing in fraction poly(n-butyl acrylate) poly(ethylene oxide) (PBA PEO) arms were under investigation. Structural characteristics was obtained on the basis Small Angle X-Ray Scattering (SAXS) investigations. The phase separated nanoscale morphology copolymer with a high PEO confirmed by Scanning Probe Microscopy (SPM) studies. modified Avrami approach used to obtain information non-isothermal crystallization...
Nuclear magnetic resonance, broadband dielectric spectroscopy and dynamic-mechanical thermal analysis were employed to study molecular dynamics of ethylene-norbornene copolymer.The experimental data indicates existence three motional processes denoted as α, β, γ in order decreasing temperature.The α relaxation is related the dynamic glass transition, while β relaxation, observed only for untreated sample, assigned short range segmental motions involving norbornene units.The due very local...
Abstract Nuclear magnetic resonance (NMR) and broadband dielectric spectroscopies (BDS) were used to analyze the molecular dynamics in P10.3H Podand. The temperature studies of NMR line spin–lattice relaxation times accompanied by DS investigation enabled us distinguish three main dynamical processes connected with motions Podand chains. In low‐temperature region was associated fast axial C 3 rotation methyl groups. Moreover, two other independent observed interpreted as (i) segmental motion...
Abstract Advances in molecular medicine related to the treatment of genetic disorders and cancer require finding new pathways for gene transfer. Nonviral delivery methods rely on application polymers, liposomes cationic lipid systems used as vehicle. Among these systems, there is increasing interest surfactants, which, due their ability complex with nucleic acids can deliver into cell DNA or RNA molecules almost any size, which unattainable viral systems.The main aim this study was determine...
