D. Dacron

Answer

To solve the question regarding the polymer obtained from the condensation of sebacic acid and hexamethylene diamine, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The two reactants are sebacic acid and hexamethylene diamine.
- Sebacic acid has the formula: HOOC-(CH2)8-COOH.
- Hexamethylene diamine has the formula: H2N-(CH2)6-NH2.

2. **Understand the Reaction Type**:
- The reaction between sebacic acid (a dicarboxylic acid) and hexamethylene diamine (a diamine) is a condensation reaction.
- In a condensation reaction, two molecules combine to form a larger molecule with the elimination of a small molecule, typically water.

3. **Write the Reaction**:
- When sebacic acid and hexamethylene diamine react, they form a polymer through the formation of amide linkages.
- The reaction can be represented as:
\[ \text{HOOC-(CH2)8-COOH} + \text{H2N-(CH2)6-NH2} \rightarrow \text{Polymer} + \text{H2O} \]

4. **Determine the Structure of the Polymer**:
- The polymer formed will have repeating units that include the amide linkages created from the reaction.
- The structure will consist of segments from both the sebacic acid and hexamethylene diamine.

5. **Count the Carbon Atoms**:
- From hexamethylene diamine, there are 6 carbon atoms.
- From sebacic acid, there are 10 carbon atoms (8 from the chain and 2 from the carboxylic groups).
- Therefore, the total number of carbon atoms in the polymer is 6 (from diamine) + 10 (from acid) = 16.

6. **Name the Polymer**:
- The polymer formed from this reaction is known as Nylon 6,10.
- The name indicates that it is derived from a hexamethylene diamine (6 carbon atoms) and sebacic acid (10 carbon atoms).

7. **Conclusion**:
- The correct answer to the question is that the polymer obtained from the condensation of sebacic acid and hexamethylene diamine is **Nylon 6,10**.

### Final Answer:
The polymer obtained from the condensation of sebacic acid and hexamethylene diamine is called **Nylon 6,10**.
