Poly(vinyl alcohol) and polyethylene polymer systems were built in order to study their transport properties (diffusion). First a verification of the AMBER force field was conducted for a poly(vinyl alcohol) system built from a chain with 145 repeating units. NPT-molecular dynamics simulations at temperatures between 400 and 527 K were performed. The results of the simulations were compared wit...

a mixture  of  sodium  lauryl  sulfate  (sls)  as  ionic  emulsifer  and  stearyl alcohol as non-ionic emulsifer was employed in a vinyl chloride emulsion polymerization  reaction  to  study  the  infuence  of  various  interactive parameters involved in the reaction system. it was found that the particle size was dependent on the amount and type of emulsifer. the average particle size of polyv...
