A) Step growth
B) Chain growth
C) Branched
D) Graft
E) none of these

Question

Quizplus · Accepted Answer

In step growth polymerization, two or more monomers react together, forming an oligomer or a small molecule that is capable of further reactions. This oligomeric species then reacts with another monomer or oligomer to form a longer chain or polymer. This process continues in a stepwise fashion until the desired polymer is formed. Chain growth polymers, on the other hand, involve the initiation and propagation of a growing polymer chain, without the formation of an intermediate oligomer. Branched and graft polymers are variations of step growth and chain growth polymers, respectively, and are not formed under the specific conditions described in the question.
