is bakelite a condensation polymer

Bakelite is the condensation polymer of phenol and formaldehyde. In practice, the phenol and formaldehyde are first polymerized to a small extent by using the proper choice of catalyst and temperature. Hence, it is a thermosetting ploymer. 284 Views. Condensation polymers: Terylene, bakelite. Some common examples of condensation polymerization are bakelite, nylon, and silicon From this table, it must be quite obvious that the main difference between both addition and condensation polymerization is that in the case of addition polymerization, the polymers are formed through the addition of monomers. Bakelite contains cross linked molecules which on heating undergo extensive cross linking in moulds and again become infusible. Teflon. Bakelite resin is a phenol formaldehyde resin formed by condensation reaction of phenol or substituted phenol with formaldehyde. Which of the following polymers are condensation polymers? 21. Dacron. It cannot be reused. Explain the difference between Buna-N and Buna-S. Ans. 4. Bakelite is a condensation polymer of formaldehyde and phenol. HCHO. It is a thermosetting phenol-formaldehyde resin formed by the condensation reaction of phenol with formaldehyde. Melamine formaldehyde resin is a condensation polymer of melamine (2, 4, 6-triamino-1, 3, 5-triazine) and formaldehyde. Acrylonitrile. The two monomers used in the preparation of dextron are. CH 3 CHO. Which one is classified as a condensation polymer? It is a thermosetting phenol-formaldehyde resin formed by the condensation reaction of phenol with formaldehyde. Bakelite, which is also known as a 'material of a thousand uses' is chemically called polyoxybenzyl methylene glycol anhydride. Neoprene. Bakelite, which is also known as a 'material of a thousand uses' is chemically called polyoxybenzyl methylene glycol anhydride. Answer. It is used for the manufacture of electrical plugs and switches. (a) Bakelite (b) Teflon (c) Butyl rubber (d) Melamine formaldehyde resin Solution: (a, d) Bakelite is a condensation polymer of phenol and formaldehyde. 3. Answer Contents. The introduction of Bakelite—the world’s first synthetic plastic—in 1907 marked the introduction of the Polymer Age. I have succeeded in preparing a solid initial condensation product, the properties of which simplify enormously all molding operations So, we can, in general, say that Bakelite is a condensation polymer or a phenolic resin. Answer. A. Dacron. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. Bakelite is obtained from phenol by reacting with (CH 2 OH) 2. 263 Views. Bakelite is the first plastic made from synthetic components. D. HCHO.
