Liitpolümerisatsioonis

Liitpolümerisatsioon is a chemical process where two or more different types of monomers react together to form a single polymer chain. This is distinct from homopolymerization, where only one type of monomer is involved. In liitpolümerisatsioon, the monomers are typically incorporated into the polymer in a specific, often alternating, sequence, although random copolymerization is also possible. The properties of the resulting liitpolümeer depend heavily on the specific monomers used, their ratio, and the polymerization conditions.

This process allows for the creation of polymers with tailored properties that cannot be achieved with homopolymers. For example, combining monomers with different characteristics can lead to improved mechanical strength, thermal stability, or chemical resistance. The reactivity of the monomers plays a crucial role in determining the structure of the liitpolümeer, influencing whether it is alternating, random, block, or graft copolymer. Different initiation and propagation mechanisms are employed depending on the specific monomers and desired polymer architecture. Liitpolümerisatsioon is widely used in the synthesis of plastics, rubbers, and fibers, finding applications in various industries from packaging to automotive.
