Polymer polymerization
WebA polymer is a large molecule or a macromolecule which essentially is a combination of many subunits. The term polymer in Greek means ‘many parts’. Polymers can be found all around us. From the strand of our DNA, … WebIt is observed in the above reaction that adipic acid and hexamethylene diamine are the two monomers that combine and react to form larger molecules or macromolecules called polymers. Here, the polymer formed is nylon-6,6, and water (H₂O) is released as a byproduct and it is a form of step-growth polymerization.

WebDec 1, 1993 · n-Butyl isocyanate (nBIC) was polymerized in bulk by the Pruitt–Baggett adduct (PBA) at −23, 0.0, and 25.0°C. Polymerization was accompanied by trimerization to the cyclicisocyanurates at all temperatures. Spectroscopic evidences supported the nylon-1 structure for both trimer and polymer. The polymer/trimer ratio and the molecular weight … WebRecently, we demonstrated a water-based emulsion polymerization method (i.e. the temperature directed morphology transformation, TDMT, method[12-14]) to produce tadpole nanostructures directly in water facilitated by a thermoresponsive block when combined with the solvent swelling-induced technique.
