Step Growth Polymer: Bakelite
- Bakelite is a type of step growth polymer.
- Step growth polymers form by a reaction between functional groups of monomers, leading to the growth of the polymer chain.
- In the case of Bakelite, the reaction occurs between phenol and formaldehyde molecules.
- This reaction results in the formation of cross-linked structures, leading to the characteristic properties of Bakelite such as high heat resistance and electrical insulating properties.
- Step growth polymers like Bakelite are known for their high molecular weight and dense network structure, which give them unique properties compared to other types of polymers.
- Bakelite is widely used in the production of various materials such as electrical insulators, automotive parts, and consumer goods due to its excellent properties.

Step Growth Polymer: Bakelite
Step Growth Polymers
Step growth polymers are formed by the reaction between two different functional groups. The reaction takes place between monomers with two or more functional groups, which react with each other to form a polymer. The reaction is gradual and occurs through the formation of intermediate species, such as dimers, trimers, and oligomers.
Bakelite
Bakelite is a step growth polymer that is formed through the reaction between phenol and formaldehyde. The reaction takes place in two stages. In the first stage, formaldehyde reacts with phenol to form a series of dimers and trimers. In the second stage, the dimers and trimers react with each other to form the final polymer.
Bakelite is a thermosetting polymer and is widely used in the manufacture of electrical components, such as switches, plugs, and sockets. It is also used in the manufacture of billiard balls, jewelry, and other decorative items.
Other Polymers
Polyethylene, Teflon, and PVC are all examples of chain growth polymers. Chain growth polymers are formed by the reaction between a monomer and a reactive intermediate, such as a free radical or an ion. The reaction takes place in a single step, and the polymer grows by the addition of monomer units to the growing chain.
Polyethylene is a common plastic that is used in the manufacture of packaging materials, such as bags, bottles, and containers. Teflon is a non-stick coating that is used in the manufacture of cookware, such as frying pans and baking trays. PVC is a versatile plastic that is used in a wide range of applications, such as pipes, cable insulation, and flooring.
In conclusion, Bakelite is a step growth polymer, while Polyethylene, Teflon, and PVC are chain growth polymers.

Of the following which is a step growth polymera)Bakeliteb)Polyethylen...
Step-growth polymerization refers to a type of polymerization mechanism in which bi-functional or multifunctional monomers react to form first dimers, then trimers, longer oligomers and eventually long chain polymers. Bakelite forms by the polymerization of phenol and formadehyde. It forms cross links between different chains of the polymer and thus forms by step-growth mechanism.
