Emulsion dispersion

Pristine   nylon−6 (white) and   nylon−6/ LNR   blends (yellow)

 films  , prepared via emulsion dispersion technique.

An emulsion dispersion is  thermoplastics or elastomers

suspended in a waterphase with help of emulsifiers.

1 Preparation

Emulsions are thermodynamically unstable liquid/liquid

dispersions that are stabilized.[1] Emulsion dispersion

is not about reactor blends for which one polymer is

polymerized from its   monomer   in the presence of the

other  polymers; emulsion dispersion is a novel method

of choice for the preparation of homogeneous blends of

thermoplastic   and   elastomer.[2] In emulsion dispersion

system the preparation of well-fined polymers droplets

may be acquired by the use of   water   as dispersing

medium. The surfactant molecules adsorb on the surface

of emulsion by creating a dispersion of droplets,[3]

which reduces   interfacial tension   and retards   particle

flocculation during mixing.[2] The molecules of surfac-

tant have   polar   and   non-polar   parts which act as an

intermediary to combine polar and non-polar polymers;

the   intermolecular   interactions between the polar and

the non-polar polymer segments resemble the macro-

scopic hydrocarbon-water interface.[2][4][5] The idea of

the emulsion dispersion inspired by emulsification of

liquid natural rubber (LNR), from   particle size anal-

ysis   and   optical microscopy   results showed that the

droplet size of emulsion of LNR with higher molecu-

lar weight is greater than that of the lower molecular

weight.[6] Emulsion dispersion was able to produce homo-

geneous  low density polyethylene   (LDPE)/LNR blends[2] and   nylon 6/LNR blends.[5] Results of   differential

scanning calorimetry (DSC) thermogram indicated a sin-

gle   glass transition temperature  (Tg) showed that the

blends were   compatible   and   Scanning Electron Mi-

croscopy   (SEM)   micrograph   showed no   phase separa-

tion  between blend components. In addition, exfoliated

HDPE/LNR/montmorillonite nanocomposites were suc-

cessfully achieved by using emulsion dispersion technique

as well.[7]
