Colloidal crystal assembly film was prepared by using monodispersed colloidal particles of cross-linked random copolymer methyl methacrylate and ethyl acrylate soap-free emulsion polymerization. The exhibited structural color when swollen with monomer. maintained even after polymerization the swelling monomer cross-linker, suggesting crystalline order successfully fixed embedded in matrix poly(ethyl acrylate) elastomer. Stretching deformation colored elastomer induced a sensitive change to...
Shape memory behavior of polymer blends consisting thermoplastic polyurethane (PU) and crystalline poly(oxyethylene) (POE) have been investigated. PU is in a rubbery state at room temperature has an ability to recover from deformed temporary shape permanent by entropic elasticity, POE role fix the crystallization solidification system. As result, excellent properties can be obtained blending elastic POE. With increasing content blend, fixity ratio below was increased almost 100%, but...

The solid state morphology of the main-chain liquid crystal BB-6 polyester was studied by small angle X-ray scattering (SAXS) method. forms isotropic, smectic A, and phases in order decreasing temperature; thereby its crystallization is taking place from A phase. SAXS for crystalline specimens prepared cooling isotropic melt at a rate 10 °C min-1 shows well-defined reflection maxima which are attributable to stacked lamellar structure. spacings distributed around 250 Å so that an appreciable...

Abstract Graft copolymers consisting of amorphous main chain, poly(methyl methacrylate) (PMMA), or acrylate) (PMAc), and crystalline side chains, poly(ethylene glycol) (PEG), have been prepared by copolymerization PEG macromonomers with methyl methacrylate acrylate (MMA x MAC , respectively). Because the compatibility PMMA/PEG PMAc/PEG, from small‐angle X‐ray scattering results, chains in graft were suggested to be homogeneous molten state. Differential scanning calorimetry (DSC) cooling...
Uniaxially oriented liquid crystalline poly(γ-benzyl l-glutamate) (PBLG) gel was prepared by cross-linking the lyotropic PBLG solution in magnetic field, and converted to poly[N5-(2-hydroxyethyl) l-glutamine] (PHEG) side-chain aminolysis reaction. The PHEG retained crystallinity after conversion from when immersed α-helix-forming solvent such as ethylene glycol. By addition of water into immersion solvent, conformational transition α-helix random coil occurred, optical anisotropy...
Abstract In this study, transparent poly(methylmethacrylate) (PMMA)‐silicone hybrid materials, P(MMA‐ co ‐SigUMAx), were prepared with methylmethacrylate (MMA) and multifunctional silicone macromonomer introduced methacryl groups. The transmittance of materials improved increase groups reached around 90% T. Atomic force microscopic analysis, scanning electron microscope examinations, copolymerization kinetics estimation by proton nuclear magnetic resonance revealed that the randomly...
