The aim of this study was to describe a simple boiling temperature soap-free emulsion polymerization for the synthesis of poly(styrene-co-acrylamide) at reduced polymerization time. FT-IR characteristic of the polymer showed that there was acrylamide group on the styrene. Thus, acrylamide was successfully incorporated into the polystyrene chain prior to electrospinning. Electrospun fibers of different diameters were fabricated from the styrene and acrylamide of different mole ratios to give poly (styrene-co-acrylamide), some of which resulted in bead formation. Many parameters can influence the transformation of polymer solutions into fibers through electrospinning. These parameters include: 1) the solution properties such as viscosity, elasticity, conductivity, and surface tension; 2) governing variables such as hydrostatic pressure in the capillary tube, electric potential at the capillary tip, and the gap (distance between the tip and the collecting screen); and 3) ambient parameters such as solution temperature, humidity, and air velocity in the electrospinning chamber. Variation and optimization of these parameters will results in fiber of different nanometer sizes that can have diverse and various applications including drug delivery, electrical and optical application etc. The poly(styrene-co-acrylamide) fiber formed is anticipated for diverse application such as Solid Phase Extraction (SPE) materials, filters, textile etc.

Can be from plant, animal and synthetic sources. Most and colors are derived from . Coal tar in itself is considered a vegan product. However, coal tar derivatives cause frequent allergic reactions, like skin rashes and hives. It has also shown to cause cancer in animals. For this reason, colors and dyes are continuously tested on animals. That's why and colors and dyes can generally not be considered vegan and I will mark them as on this page.
