Which consequence arises when a catalyst contamination alters adsorption constants during olefin polymerization?

💡 Explanation

Polymerization kinetic reactions speed shifts through alteration in the Langmuir adsorption isotherm. Because catalyst site blockage preferentially inhibits chain termination over propagation, increased chain branching results and leads to structural irregularities rather than higher molecular weight where cleaner catalysts enhance yields. Termination becomes limited; lowering thermal threshold is incorrect.
