The structures of honeycomb-patterned thin polymer films fabricated by casting polystyrene solution under humid conditions were controlled by illumination of ultraviolet (UV) light by the assistance of an added light-sensitive amphiphilic copolymer (A ls ) in the casting solution. A ls was synthesized through the radical copolymerization of ruthenium(4-vinyl-4′-methyl-2,2′-bipyridine)bis(2,2′-bipyridine)bis(hexaflurophosphate)...
The empirical equations of configurational energy U conf. and configurational heat capacity C P.conf. have been derived for polymer and simple liquids including amorphous polymer liquids, rare gas liquids, and non-polar and polar liquids based on experimental data over the temperature range up to vapour-liquid critical temperature T C . The equations obtained in this work are:...
The melting temperatures (T m ) of branched polyethylene (B-PE) have been measured over the pressure range up to 2 GPa by use of a high-pressure X-ray diffraction apparatus. The T m -P curve for B-PE is expressed as (T m /T m,0 ) c = (P + P 0 )/a where T m,0 is the T m at atmospheric pressure, c = 4.788, P 0 ...
The simple P-V relation V x (P, T) = V x (P 0 , T)/{A x (T)[P + P x (T)] mx } and T-V relation ln(T/T 0 ) = CZ nx , where T 0 = 1 K, T ≥ 1 K, Z = {V x (P,T) - V(P,1)}/V x (P,T) derived in previous works have been used to calculate the compressibility and thermal expansion coefficient for crystalline polymers...
The simple P−V relation Vx(P, T) =Vx(P0, T)/[Ax{P + Px(T)}mx] and T−V relation ln T =C[{Vx(P, T)−V(P, 0)}/Vx(P, T)]nx derived in previous works have been used to calculate the compressibility and thermal expansion coefficient by βT = mx/{P + Px(T)} and αp = {Vx(P, T) − V(P, 0)}/{V(P, 0)nxT ln T}. The subscript x means a state of material such as x = g for glass state and x = l for liquid state, mx...
