## Description

This MCP server provides specialized chemical engineering tools to analyze polymer structures. It allows AI agents to determine the degree of polymerization ($DP_n$ and $DP_w$), calculate the number of repeat units, and determine the Polydispersity Index (PDI) using monomeric and molecular weight data. Use `get_molecular_distribution_summary` for a complete overview of molecular characteristics or `calculate_pdi` to assess the breadth of molecular weight distribution.

## Tools

### calculate_dp_from_mn
Determines the number-average degree of polymerization using the number-average molecular weight and the monomer mass

### calculate_dp_from_mw
Determines the weight-average degree of polymerization

### calculate_pdi
Calculates the Polydispersity Index to understand the breadth of the molecular weight distribution

### get_molecular_distribution_summary
Provides a comprehensive overview of the polymer's molecular characteristics from all available weight averages

```

## Frequently Asked Questions

**What is the Polydispersity Index (PDI)?**
The PDI is a measure of the distribution of molecular masses in a polymer sample. A PDI of 1 indicates a monodisperse sample where all chains are the same length.

**How do I calculate the degree of polymerization?**
You can use the `calculate_dp_from_mn` tool by providing the monomer weight and the number-average molecular weight.

**Can I get a full summary of my polymer sample?**
Yes, the `get_molecular_distribution_summary` tool provides a comprehensive overview including $DP_n$, $DP_w$, and PDI.
