Final answer:
Polymeric stabilization refers to the process in which a polymer attains stability, with variations at different concentrations. In condensation polymerization, polymers can be affected by monomer concentration, temperature, and pressure, with low concentrations typically yielding lower molecular weight polymers and high concentrations producing higher molecular weight polymers.
Step-by-step explanation:
Polymeric stabilization refers to the process in which polymer chains obtain stability, especially at varying concentrations. During condensation polymerization, which is a type of step-growth polymerization, polymers like Dacron and Nylon 66 are formed by combining two different monomers that react and lose a small molecule, typically water. This process is distinct from addition polymerization, which usually involves the growth of polymers by carbon-carbon bond formation, whereas step-growth polymers grow by forming carbon-heteroatom bonds (C-O & C-N).
The stability and properties of the resulting polymer can be influenced by altering the concentration of monomers as well as the process conditions such as pressure and temperature. At low concentrations, the polymerization may proceed more slowly and produce a lower molecular weight polymer. At high concentrations, the reaction rate and molecular weight of the polymers tend to increase. The final characteristics of polymeric materials are highly dependent on these polymerization conditions.
Condensation polymers like PET (polyethylene terephthalate) are commercially significant and exhibit manipulation of properties through control over monomer concentration and reaction environment, which underscores the importance of understanding the polymeric stabilization process from low to high concentrations.
