What are the factors affecting the molecular weight of a polymer? Low Molecular Weight polymers have lower properties due to lack of chain entanglement and higher molecular mobility. Shorter chains have more end groups which increase free volume and molecular mobility which makes it easier for the polymer chains to respond to stresses.
What are the factors affecting a polymers properties? The processing conditions which can affect the properties of the polymer include the temperature and pressure used during the polymerization, the solvent in which the polymer is polymerized, the types of monomer units used, the concentration of monomers in the reaction, the reagent which is used to initiate the
How does molecular weight affect properties of polymers? The lower the molecular weight, lower the transition temperature, viscosity, and the mechanical properties. Due to increased entanglement of chains with increased molecular weight, the polymer gets higher viscosity in molten state, which makes the processing of polymer difficult.
What does molecular weight depend on? The weight average molecular weight depends not only on the number of molecules present, but also on the weight of each molecule.
