Polymerization Mechanisms starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Polymerization Mechanisms.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A student observes that the polymerization of styrene proceeds rapidly after the addition of benzoyl peroxide. What type of polymerization is this?
Calculate the degree of polymerization if the molecular mass of a polyethylene sample is 140,000 g/mol and the monomer (ethylene) has a molar mass of 28 g/mol.
Describe the propagation step in free radical polymerization.
Describe the role of an initiator in free radical polymerization.
Explain the difference between homopolymerization and copolymerization.
Explain why addition polymerization is also called chain-growth polymerization.
Explain why condensation polymerization can produce both linear and cross-linked polymers.
In a laboratory experiment, a student mixes adipic acid and hexamethylenediamine and heats the mixture. Which type of polymerization is taking place?
In the context of polymerization, what does the term 'degree of polymerization' refer to?
Name the initiator commonly used in the free radical polymerization of ethene.
What is the main difference between addition and condensation polymerization?
What is the main difference between cationic and anionic polymerization mechanisms?
What is the main function of a catalyst in coordination polymerization?
