Question

For a linear polymer molecule, the total chain length l depends on?

1) The number of monomer units in the polymer chain
2) The molecular weight of the polymer
3) The degree of polymerization
4) The polymerization reaction conditions

Answer 1

The chain length of a linear polymer is determined by the number of monomer units, the degree of polymerization, the molecular weight, and the polymerization reaction conditions.

Step-by-step explanation:

For a linear polymer molecule, the total chain length l depends on several factors:

1. The number of monomer units in the polymer chain: The more monomer units there are, the longer the chain length.
2. The degree of polymerization: This refers to the number of monomer units in the polymer chain. A higher degree of polymerization leads to a longer chain length.
3. The molecular weight of the polymer: The molecular weight is directly related to the chain length. Higher molecular weight polymers have longer chains.
4. The polymerization reaction conditions: The reaction conditions, such as temperature and pressure, can affect the chain length of the polymer formed.

Overall, the chain length of a linear polymer is determined by the number of monomer units, the degree of polymerization, the molecular weight, and the polymerization reaction conditions.
