In the first case, the "repeating unit" consists of one of each monomer, so that they alternate in the chain, similar to the so-c… Southern Mississippi. (The two solutions are not miscible so the reaction can only occur at the interface. The by-product again here is water which is mostly removed. In condensation polymerisation, a small molecule is formed as a by-product each time a bond is formed between two monomers. Broadly polymerization can be classified into two categories, 1. P. J. Flory modified the original classification of Carothers to emphasize the mechanism of the polymerization. A polymer formed by direct addition of repeated monomers without the elimination of by product molecules is called addition polymers. Today, many scientists/engineers around the world are working on creating new polymers to meet the specific needs for better physical properties. Step-Growth or Condensation Polymerization 2. … Polymers are very large molecules that are made by combining smaller molecules, called monomers, together. Students will describe step-growth polymerization. Further contrasts with condensation polymers. (Neither reagent is soluble in the other's solvent. A hydrogen moves from the alcohol to the nitrogen, while the This same polymer with the trade name of mylar when made as The urethane functional groups are Some polymers are made via condensation polymerisation. Students will know what a step-growth polymerization is. This can be accomplished by tilting the beaker slightly and pouring the solution down the side of the beaker. Grades: 9-12 A. H2O B. NH3 C.
