Methods of Polymerisation — Prelims Strategy

Prelims Strategy

To excel in NEET questions on 'Methods of Polymerisation', a systematic approach is essential. Firstly, thoroughly understand the core definitions and distinctions between addition and condensation polymerisation.

Create a mental checklist: 'Does it involve C=C bonds?' (likely addition) and 'Are small molecules eliminated?' (likely condensation). Memorize key examples for both categories, linking each polymer to its specific monomer(s) and polymerisation method.

For addition polymerisation, pay attention to the three steps of free radical mechanism (initiation, propagation, termination) and the role of initiators. For condensation, remember that it's a step-growth process and identify common by-products like water.

Practice identifying monomers from given polymer structures and vice-versa. Be wary of trap options that mix characteristics of different polymerisation types or present incorrect monomer-polymer pairings.

Use flashcards for quick recall of polymer names, monomers, and methods. Focus on conceptual clarity rather than rote memorization alone, as understanding the underlying chemistry helps in solving trickier questions.
