Structure of Dehydrochlorinated Polyvinylchloride

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1969
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。

Performance Study of Cellulose Acetate Blended Polyvinylchloride Membranes [PDF]

open access: yesNature Environment and Pollution Technology, 2020
In this paper, polymeric membranes were prepared by uniformly dispersing the cellulose acetate, polyethylene glycol and polyvinyl pyrrolidone particles in a polyvinyl chloride matrix for resolving the demand for azeotropic mixture separations.

Properties of thermoshrinked films based on polyvinylchloride [PDF]

open access: yes, 2012
Dependence of thermal shrinkage of films based on polyvinylchloride (PVC) on temperature is established. The technique of determining PVC film shrinkage speed within a wide interval of temperatures is developed.

Modification of Polychloroprene with Polyvinylchloride

open access: yes, 1985
Polychloroprene (neoprene) has been blended with polyvinylchloride (PVC) in different proportions using a new stabiliser system (magnesium oxide and zinc oxide with stearic acid) for PVC.

Fluctuation-induced tunneling conduction in carbon-polyvinylchloride composites

open access: yes, 1978
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]

open access: yesPakistan Journal of Analytical & Environmental Chemistry, 2010
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 ...
