What are the 3 types of polymerization?

What are the 3 types of polymerization?

There are three different types.

• Linear polymers: Consists of a long and straight-chain of monomers. PVC is a linear polymer.
• Branched polymers: They are linear polymers containing some branches.
• Network or cross-linked polymer: Polymers having cross-linked bonds with each other is called cross-linked or network polymer.

What are the methods of polymerization?

Methods include emulsion polymerization, solution polymerization, suspension polymerization, and precipitation polymerization. Although the polymer dispersity and molecular weight may be improved, these methods may introduce additional processing requirements to isolate the product from a solvent.

What is Topotactic and Epitactic reaction?

Epitactic and topotactic reactions Epitactic: structural similarity restricted to the surface / interface. between two crystals layer. Topotactic: Structural similarity through the crystal. The ease of nucleation depends also on the actual surface structure of the reactants.

What is polymerization and its type?

Polymerization is the process of forming larger macromolecules from simpler sub-units known as monomers. The two major types of polymerization are addition polymerization and condensation polymerization.

What is polymerization mechanism of polymerization?

The mechanism of polymerization involves addition of a proton acid to aziridine to produce the corresponding aziridinium ion (6; equation 1). If an alkylating agent is used as initiator, the alkylated monomer will transfer a proton to a monomer thus producing the same initiating species (equation 2).

What are two methods of polymerization?

There are two basic types of polymerization, chain-reaction (or addition) and step-reaction (or condensation) polymerization.

What is a topotactic process?

A topotactic reaction is a chemical solid-state reaction such that the orientations of the product crystals are determined by the orientation of the initial crystal. The same symmetry rules apply for the domains as for phase transitions.
