Structure of Dehydrochlorinated Polyvinylchloride
ポリ塩化ビニルの脱塩化水素反応を粉末状およびジメチルホルムアミド溶液中でおこない,得られた脱塩化水素ポリ塩化ビニルの構造について比較検討した。脱塩化水素されたポリ塩化ビニルの共役ポリェン数は,粉末状で得られたものは,3~6程度であり,ジメチルホルムアミド中で得られたものは3~14程度であった。また,得られた脱塩化水素ポリ塩化ビニルの二重結合は,粉末状よりのものは730cm-1近くに吸収を示し,ジメチルホルムアミド中よりのものは,1000cm-1近くに吸収がみとめられ,両者の間に明らかに違いのあることをみとめた。

Fluctuation-induced tunneling conduction in carbon-polyvinylchloride composites
We present evidence that in carbon-polyvinylchloride composites, consisting of aggregates of carbon spheres (100-400) dispersed in the insulating matrix, the electrical conductivity can be ascribed to a novel mechanism of tunneling with potential-barrier

Effect of Various Additives on the Physical Properties of Polyvinylchloride Resin [PDF]
The compounding of Polyvinylchloride (PVC) with some additives was studied for the enhancement of physical and mechanical properties. Two categories of formulations (un-plasticized and plasticized PVC) were prepared with PVC (K value ranging from 60 to ...
