Multiple-choice question: During suspension polymerization, excessive iron content in the VCM monomer prolongs the polymerization induction period; it slows down the reaction rate, deteriorates the thermal stability of the product, and also reduces the dielectric properties of the product. A. Longer, better B. Shorter, better C. Shorter, worse D. Longer, worse Answer: D, Longer, worse
During suspension polymerization, excessive iron content in the VCM monomer leads to an extended polymerization induction period (c), a slowdown in the reaction rate, a deterioration in the thermal stability of the product, and a reduction in its dielectric properties.
