Answer #1

Initiator used in the bulk polymerization of PMMA is redox pair (double radical initiator)   [benzoyl peroxide (BP) - dimethylparatohidine (DMPT)] .

Initiator used in the emulsion polymerization of PMMA is potassium peroxo-disulfate.

These initiators cannot be used interchangeably in either method.
Emulsion polymerization requires water soluble initiator (potassium peroxo-disulfate.) and redox pair (double radical initiator)   [benzoyl peroxide (BP) - dimethyl paratohidine (DMPT)] used in the bulk polymerization of PMMA is not water soluble.

4) If the number-average degree of polymerization for polystyrene obtained by the bulk polymerization of styrene at 60°C is 1000, what would be the number-average degree of polymerization if the polymerization were conducted in a 10% solution in toluene (900 g of toluene per 100 g of styrene) under otherwise identical conditions? The molecular weights of styrene and toluene are 104.12 and 92.15, respectively. Assume free-radical polymerizationa that includes chain-transfer termination, as well.
