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