Glyptal. Which one is classified as a condensation polymer? This polymer is used in manufacturing of paints and laquers. Check Answer and Solution for above question from Chemistry in Polymers - Tardigrade Glyptal. 3. Be the first to write the explanation for this question by commenting below. Example: Buna-S or styrene-butadiene rubber is a copolymer formed from styrene and butadiene. Neoprene - - Formed by free radical polymerization of chloroprene ( 2-chloro-1, 3-butadiene ). Note: Biopolymers include various biomolecules such as carbohydrates, proteins etc. Question 2. Correct Answer: Neoprene. The monomers used are lactic acid and glycolic acid. Condensation polymers are obtained from bifunctional molecules (monomers) with the elimination of smaller molecules whereas addition polymers are obtained from monomers containing multiple bonds. It is added to lubricants to reduce surface friction. Glyptal can be used as a substitute for dark-coloured Copal resins. NEET Chemistry Polymers questions & solutions with PDF and difficulty level Add 2 mL of glycerol. Difference between addition polymerisation and condensation polymerization: Addition polymer: Simple monomer units combine together to form polymer. - Homopolymer - wherein - Superior resistance to vegetable and mineral oils. Homomer: In this type, a single type of monomer unit is present. [CBSE AIPMT 2012] A. Dacron. Glyptal is a synthetic polymer. HCHO. Addition and Condensation Polymers Addition polymers In the molten state polymers can be spun into fibres. Post Answer. 4. [CBSE AIPMT 2012] A. Glyptal is a type of alkyd that contains polyester with fatty acids. 1) Nylon-66 2) Polyester 3) PVC 4) Glyptal 17. It is an addition polymer. Some polymers are made via condensation polymerisation. Neoprene is made from monomer chloroprene (2-chlorobuta-1,3-diene). Teflon. (a) Glyptal (b) Nylon-6, 6 (c) PTFE (d) Dacron. 2. Obtain a paper cup. Neoprene is made from monomer chloroprene (2-chlorobuta-1,3-diene). Glyptal is a condensation polymer formed by the reaction between ethylene glycol and phthalic acid. Which of the following an addition (chain growth) polymer? Check Answer and Solution for above quest Polyester is a category of polymers that contain the ester functional group in their main chain. Glyptal or Alkyl Resin. CH 3 COCH 3. Neoprene. C. Melamine. As discussed in. 2. Dacron ( also known as terylene) is a polyester made by condensation polymerisation of ethylene glycol and dimethyl terephthalate. B. Which one of the following is not a condensation polymer . Which of the following statements is false? Answer. A: Glyptal, the cross-linked polyester, is the thermoset polymer. KCET 2009: The condensation polymer among the following is (A) PVC (B) Polyethene (C) Rubber (D) Protein. Glyptal resins are polyester plastics formed by the esterification-polymerisation reaction which occurs between polyols and polybasic organic acids or anhydrides. Dacron, Melamine and Glyptal are condensation polymers. It did not soften when heated. Bakelite is obtained from phenol by reacting with (CH 2 OH) 2. term polymer is defined as very large molecules having high molecular mass (103-107u). Glyptal is a copolymer of ethylene glycol and phthalic acid. Polymer formed from more than one kind of monomer unit is a copolymer or mixed polymer. Place 5 g of phthalic anhydride and 0.25 g of sodium acetate in a test tube. Explanation: No explanation available. The polymer reaches its melting temperature (T m in the phase diagram) and becomes molten (progressing along the line from c to d). Option 4) Neoprene . These are also referred to as macromolecules, which are formed by joining of repeating structural units on a large scale.
