Based on the mode of polymerisation, it is classified into; Addition polymers: Polymers are formed by the repeated addition of monomers with double and triple bonds. Fibers. It allows ethene molecules to join together to form a single product, so it is an example of an addition reaction. Which of the following represents the example of homopolymer? It is used for … (b) What are biodegradable polymers? The monomers used are unsaturated compounds like alkenes, alkadienes and their derivatives. 20: Which of the following is an addition polymer? Examples – Bakelite, melamine, etc. Modelling addition polymers. Bakelite, formed from the condensation reaction of phenol with formaldehyde, became hugely popular – perhaps you have seen products with Bakelite, such as … Familiar examples of cross-linked polymers are Bakelite, rubber, and casting (boat) resin. They have a stronger covalent bond in comparison to other linear polymers. Answer: Bakelite is the condensation polymer of phenol and formaldehyde. Question 11. 1) Polythene 2) PVC Polyacrylonitrile is an example of (a) addition polymer (b) condensation polymer (c) natural polymer (d) None of these. These polymers contain bi-functional and tri-functional monomers and strong covalent bonds between various linear polymer chains. It is because of the unique properties it possesses. Polymers can also be classified on the basis of mode of polymerisation into two sub groups. (a) PMMA (b) Nylon- 6, 6 (c) Dacron (d) Bakelite.

A hard, infusible, and chemically resistant plastic, Bakelite was based on a chemical combination of phenol and formaldehyde (phenol-formaldehyde resin), two compounds that were derived Differentiate between the modes of formation of an addition polymer and a condensation polymer. uses no catalyst. What is its use? Which compound form linear polymer due to H-bond? -It requires two like molecules. What is bakelite? The catalyst used in the manufacture of polythene by Ziegler method is The best example is polymerization of ethylene. The reaction is shown in the graphic on the left. EXAMPLES-Bakelite,formaldehyde etc. Ans. 18: Which is used in formation of nylon-66? These included other types of cast phenolic resins similar to Catalin , and urea-formaldehyde resins, which could be made in brighter colors than polyoxybenzylmethyleneglycolanhydride. Some common examples are Proteins (which are found in humans and animals alike), ... thermosetting polymer is that of Bakelite, which is used in making electrical insulation. Addition Polymers The addition polymers formed by the polymerisation of a single monomeric species are known as homopolymers. Question 47. Addition polymers are generally formed by chain growth polymerisation. They have a very strong intermolecular force. Bakelite done clear. The double bonds in monomers break and they join to form a big molecule. A) Both addition polymers and condensation polymers contain all of the atoms of the monomers. Which of the following polymer is an example of fibre [AIIMS 2000; Pb. Most natural polymers being employed at early stage of human society are of condensation type. The first truly synthetic plastic was bakelite, developed by Leo Baekland between 1905 and 1914.
