A lump of non-dispersed polymer is known as what?

• A. Gel
• B. Resin
• C. Microbead
• D. Microgel

Answer: (D)

In polymers, a gel is a crosslinked network that traps solvent and doesn’t flow, so it behaves like a soft lump rather than a dissolved polymer. When that gel exists as a small, discrete particle, we call it a microgel. So a lump of non-dispersed polymer that maintains a swollen, network‑like structure but is small enough to be a distinct particle fits the term microgel best. The other options describe either rigid, non-swelling forms (resin, microbead) or a bulk, macroscopic gel, not a small gel particle.
