Question

Найдите молекулярную массу поливинилхлорида, степень полимеризации которого составляет 50000

Answer 1

(-CH2-CH(Cl)-)n - поливинилхлорид
n - степень полимеризации,составляющая 50 000.
Найдем молекулярную массу одного структурного звена:
Mr(-CH2-CH(Cl-) = 35,5 + 12*2 + 3 = 62,5
Теперь умножим это число на количество структурных звеньев,то есть степень полимеризации:
62,5*50 000 = 3 125 000 а.е.м
Ответ:3 125 000 а.е.м

Answer 2

Molecular Mass of Polyvinyl Chloride (PVC) with a Degree of Polymerization of 50000

Polyvinyl chloride (PVC) is a widely used polymer in various applications. To calculate the molecular mass of PVC with a degree of polymerization of 50000, we can use the formula:

Molecular Mass = (Degree of Polymerization) * (Molar Mass of Monomer)

Given that the molar mass of the monomer unit of PVC is approximately 62.5 g/mol we can calculate the molecular mass as follows:

Molecular Mass = 50000 * 62.5 g/mol

Molecular Mass = 3,125,000 g/mol

Therefore, the molecular mass of polyvinyl chloride with a degree of polymerization of 50000 is approximately 3,125,000 g/mol.

This calculation is based on the molar mass of the monomer unit of PVC and the degree of polymerization, as per the provided search snippets
