What properties are affected by the degree of polymerization explain?
This means that the degree of polymerization indicates how the ratio of the molecular weights increases. o Polymerization and in particular the degree of polymerization has an impact on many of its properties. The affected properties are tensile strength, impact strength, resistance to cracking, and viscosity.
What is chain reaction polymerization?
Chain‐reaction polymerization is one of the two processes for converting monomer to polymer; the other is step‐reaction polymerization. Polymerization occurs by the propagation of the reactive center through successive additions of large numbers of monomer molecules in a chain reaction.
What is chain step growth polymerization?
Step-growth polymerization refers to a type of polymerization mechanism in which bi-functional or multifunctional monomers react to form first dimers, then trimers, longer oligomers and eventually long chain polymers.
What is chain growth polymerization with example?
Polycondensation is a kind of polymerization whose chain growth is based on condensation reaction between two molecules with various degree of polymerization. The typical example are polyesters, polyamides and polyethers.
What is difference between chain growth and step growth polymerization?
The main difference between chain growth polymerization and step growth polymerization is that chain growth polymerization has a growth a polymer chain at its ends whereas step growth polymerization has a combination of oligomers to form a polymer chain.
What is the difference between step and chain polymerization process?
The main difference is this: In a step growth reaction, the growing chains may react with each other to form even longer chains. But in an addition polymerization, only monomers react with growing chains. Two growing chains can’t join together the way they can in a step growth polymerization.
What is step growth polymerisation explain with an example?
Step-Growth Polymerization: Step-Growth Polymerization is a type of polymerization which sees bi-functional & multifunctional monomers reacting to form dimers, then trimers, then oligomers and finally long chain polymers. Example: Polyethylene Terephthalate.
What are types of polymerization?
There are two general types of polymerization reactions: addition polymerization and condensation polymerization. In addition polymerization, the monomers add to one another in such a way that the polymer contains all the atoms of the starting monomers. Ethylene molecules are joined together in long chains.
Is Orlon chain growth polymer?
Chain growth polymerisation (or addition polymerisation) involves homopolymerisation only. Examples of such polymers include polythene, orlon and teflon.
Is Glyptal chain growth polymer?
Nylon, Dacron and Glyptal polymerize by the step-growth polymerization process.
Which of the following is a chain growth polymer?

Which of the following is a chain growth polymer Orlon?
Out of given polymers, teflon is a chain growth polymer as the molecules of tetrafluoroethene (monomer) simply add together to form the polymer.
Which of the following is not a chain growth polymer?
Terylene is formed by ethylene glycol and terephthalic acid. Was this answer helpful?
Is nylon 6 a chain growth polymer?
Making nylon from a diacid and a diamine is a step-growth polymerization. So is making nylon from an amino acid. Making nylon from lactams is usually a chain-growth polymerization.
Is Terylene is a condensation polymer?
Terylene is the product of condensation polymerisation, In this polymerisation repetitive condensation takes place between two bi-functional monomers known as ethylene glycol and Terephthalic acid and produces high molecular mass condensation polymers. Terylene is also called Dacron,Terylene is also called polyester.
Which of the following is not condensation polymer?
-Examples of molecules that undergo condensation polymers are Nylon-6, Dacron (or terylene) and Glyptal, etc. So, the correct answer is “Option B”.
Is nylon 6/6 a condensation polymer?
It is a semicrystalline polyamide. Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers.
Is DNA a condensation polymer?
DNA (deoxyribonucleic acid) is an organic polymer made by the condensation polymerisation of repeating units (monomers) called nucleotides.
Which of following is condensation polymer?
Dacron is a condensation polymer.
Which is classified as condensation polymer?

Which is condensation polymer example?
Examples of naturally occurring condensation polymers are cellulose, starch, the polypeptide chains of proteins, and poly(β-hydroxybutyric acid), a polyester synthesized in large quantity by certain soil and water bacteria.
Is PVC and additional polymer?
Polyvinyl choride is abbreviated to PVC. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene (vinyl chloride) monomer. This polymerisation reaction proceeds by a free-radical mechanism.
Is PVC a polymer?

Which polymer is formed by condensation polymerization?
4 Polyamide or nylon (PA) Polyamides are condensation polymers made from diamines and diacids and are named according to the number of carbon atoms in the starting materials, e.g. Nylon 6,6 is produced from hexamethylene diamine H2N–(CH2)6–NH2 and 1,6-hexanedioc acid HOOC–(CH2)4–COOH (commonly known as adipic acid).
