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