Oligomers as Compatibilizer of Polymer Alloys

Effects of compatibilizer on immiscible polymer blends near phase inversion

e consider the effects of adding a PIB-PDMS diblock copolymer as a compatibilizer in model lends composed of polyisobutylene PIB and polydimethylsiloxane PDMS . The ratio of PIB to DMS was varied from 20:80 to 80:20 and, hence, these blends are dubbed “concentrated” blends. ost experiments were conducted on blends containing 0.01 or 0.1 wt. % compatibilizer. All lends had a droplet-matrix morph...

Application of Oligomers with Urea Linkage as Flame Retardant and Antibacterial Materials in Jute Fabric

Feasibility of Polysulfone as Base Polymer in a Polymer Inclusion Membrane: Synthesis and Characterisation

Polysulfone was investigated as an alternative base-polymer for polymer inclusion membranes (PIM’s) that could withstand harsh environmental conditions and have good transport efficiency of metal ions. PIM’s were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier in the absence of a plasticizer. Chromium (VI) was used as standard to study the extraction efficiency of the ...

Drop deformation, breakup, and coalescence with compatibilizer

The effect of copolymers on the breakup and coalescence of polybutadiene ~PB! drops in polydimethylsiloxane ~PDMS! is studied using a four-roll mill flow cell. Copolymers are produced at the interface by a reaction between functionalized homopolymers. They reduce the interfacial tension and thus enhance breakup; they also inhibit coalescence of drops. Under the conditions of our experiments, th...
