Polybutadiene forms by linking many 1,3-butadiene monomers to make a much longer polymer chain molecule. In terms of the connectivity of the polymer chain, butadiene can polymerize in three different ways, called cis, trans and vinyl. The cis and trans forms arise by connecting the butadiene molecules end-to-end, so-called 1,4-polymerisation.
Another application of polymer solutions includes the manufacture of fibers by wet or dry spinning or plastic films. Disadvantages of solution polymerization are decrease of monomer and initiator concentration leading to reduction of reaction rate, lower volume utilization of reactor, additional cost of the process related to solvent recycling ...
Oven-hardenable PVC plastisol, "liquid polymer clay," is a complement to polymer clay that can be used as an adhesive to combine pieces, or to create various effects. Pigments, chalk pastel, and regular polymer clay can be added to make colored liquid clay. The liquid can also be poured into molds to produce cast parts. [citation needed]
PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid.PBAT is produced by many different manufacturers and may be known by the brand names ecoflex, Wango, Ecoworld, Eastar Bio, and Origo-Bi.
Hydroxyl-terminated polybutadiene (HTPB) is an oligomer of butadiene terminated at each end with a hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers. HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup.
Simple clay vessels such as bowls and cups of various sizes can be formed and shaped by hand using a methodical pinching process in which the clay walls are thinned by pinching them with thumb and forefinger. It is a basic pot making method often taught to young children or beginners. The process begins with a ball of clay.
