Copolymers starts at 12 and continues till grade 12.
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 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 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.
Describe the main difference between a random copolymer and a block copolymer.
Describe the structure of a graft copolymer.
Explain the difference between statistical and alternating copolymers.
Explain the term 'sequence distribution' in the context of copolymers.
Explain what is meant by the term 'monomer reactivity ratio' in copolymerization.
Explain why copolymers are often used instead of homopolymers in industrial applications.
Explain why the physical properties of copolymers can be different from those of their homopolymer counterparts.
Name two common methods used to synthesize copolymers.
State one advantage and one disadvantage of using copolymers over homopolymers.
State one example of a commercial product made from a copolymer.
