In a linear polymer, the monomeric units are linked together to form long straight chains. The cross linked or branched chain polymers compared to linear polymers have higher ___________________?
Correct answer: D. Hardness, rigidity & brittleness
- A. Densities
- B. Melting point
- C. Tensile strength
- D. Hardness, rigidity & brittleness
Explanation
Branching and cross-linking restrict polymer-chain movement, increasing hardness and rigidity while reducing flexibility. The same restriction usually makes the material more brittle than a comparable linear polymer.
