QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Copolymers.
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 12
A copolymer is made from monomers A and B. If the polymer chain consists of long sequences of A followed by long sequences of B, what type of copolymer is this?
A copolymer is synthesized by free radical polymerization of monomers X and Y. If the reactivity ratio of X is much greater than 1 and that of Y is much less than 1, what type of sequence distribution is expected?
A copolymer is synthesized from 60% monomer A and 40% monomer B. If the resulting polymer has a random arrangement of monomers, what type of copolymer is it?
Describe how the composition of a copolymer can be determined experimentally.
A copolymer contains 70% monomer A and 30% monomer B by mole. If the molar mass of A is 100 g/mol and B is 200 g/mol, what is the average molar mass per repeat unit?

A copolymer in which the two monomers are arranged in an alternating fashion is called an __________ copolymer.
Fill in the blank: A ________ copolymer consists of a main chain formed from one type of monomer with branches of another type of monomer attached to it.
Fill in the blank: In a ________ copolymer, the sequence of monomers is irregular and does not follow a specific pattern.
Fill in the blank: The ________ copolymerization technique is often used to produce latex paints and synthetic rubbers.
Is it possible for a copolymer to be made from more than two types of monomers? Yes or No.
True or False: Copolymers can be used to improve the compatibility of two otherwise immiscible polymers.
True or False: Copolymers can only be synthesized by addition polymerization.
True or False: Graft copolymers have a branched structure.
