is polystyrene a condensation polymer

At room temperature, the thermoplastic polymer is a solid but when heated above 100 °C it flows. Answer to Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer, or a block polymer. The formation of a polyester follows the same procedure as in the synthesis of a simple ester. Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer or a block polymer. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation. Polystyrene is a hard, brilliantly transparent, stiff resin. Condensation polymerisation. Polyamide. Privacy If both moieties are difunctional, the condensation product is a linear polymer, and if at least one of the moieties is tri- or tetra-functional, the resulting polymer is a crosslinked polymer Styrene consists of a benzene ring (a six membered ring with three double bonds) bonded to an ethene chain. -It requires two like molecules. *Addition polymerization -The addition polymerization means that two monomers react with each other and no other small molecules are generated. There are two types of Condensation polymers: 1. The history of PUs started in 1937 when Dr Otto Bayer of Bayer Germany invented the diisocyanate polyaddition process. It is used as friction modifier. & In condensation polymerisation, a small molecule is formed as a by-product each time a bond is formed between two monomers. Show Video. Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer, or a block polymer. Terms Polystyrene is used in insulation and in molded items such as coffee cups. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight. It is added to lubricants to reduce surface friction. [For more information about this polymer, see Ibid., Volume 1, page 216.] The molecule most commonly split out between monomers to make a condensation polymer is Learn vocabulary, terms, and more with flashcards, games, and other study tools. Examples: Nylon, terylene, Bakelite. Protein is a natural polymer. You should be able to draw a short section of a polymer given the monomer units (and vice versa). Polyesters such as PET (polyethylene terephthalate) are condensation polymers. Answer/Explanation. Because the ionic strength of urine is equivalent to an 0.1 M NaCl solution, this superabsorbant polymer, which can be found in disposable diapers, can absorb up to 60 times its weight in urine.

Polystyrene is an aromatic polymer and has many uses including protective packaging, in trays, as … Here ethylene (ethene) is the monomer, and the corresponding linear polymer is called high-density polyethylene (HDPE). Privacy Polystyrene is … Polystyrene b. Teflon c. Polyvinychloride d. polypropylene e. dacron View desktop site. & The process is known as condensation polymerisation - forming water molecules together with polyester molecules. In the repeat unit In the repeat unit above shown the R … The synthesis is shown below. Start studying Chem Homework Polymers. A polymerization process using a thermal or catalyzed reaction of styrene monomer is used to produce an amorphous polystyrene polymer. For e.g., Nylon - 6, 6 is formed by condensation polymerization of adipic acid and hexamethylenediamine. Check Answer and Solution for above question The only difference is that both the alcohol and the acid monomer units each have two functional groups - … D) Condensation polymers contain all of the atoms of the original monomers, but addition polymers do not. Polystyrene is made from the monomer styrene which is a liquid petrochemical. (A) Polystyrene (B) PAN (C) Neprene (D) Polyethyleneglycol terephthalate. Which of the following is a condensation polymer ? Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer or a block polymer. Polyvinyl chloride, Bakelite and polystyrene are some of the examples of polymers. Figure \(\PageIndex{3}\): Polystyrene synthesis and structure. Dextron is a polyacetic acid polyglycolic acid polymer. Polystyrene can be solid or foamed. Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat. DVB has vinyl groups (-CH=CH 2) at each end of its molecule, each of which can be polymerized into a polymer chain like any other vinyl group on a … Both are formed differently, and have distinct structural features. What is Bakelite? POLYAMIDE Polyamides are a group of condensation polymers commonly known as nylon. Best Answer 100% (6 ratings) Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat view the full answer. H2O.
