| Introduction |
This section describes how to find polymer information with a molecular formula using Explore by Molecular Formula. |
| Molecular formulas |
Many compounds may share a molecular formula. They are not unique descriptors for a chemical compound. |
| Preview |
Locating relevant polymers containing a molecular formula of interest is a 2-step process:
- Locate matches on a known polymer formula
- (Optional) Refine results, based on precision criteria
|
| Example |
Locate information about homopolymers of this monomer:
|
| Locate formula matches |
Follow these steps to locate matches on a known polymer formula. |
| Step |
Do this |
| 1 |
From the New Task dialog box, click Explore  . |
| 2 |
From the Explore dialog box, click Molecular Formula  . |
| 3 |
The Explore by Molecular Formula dialog box appears. Type the polymer formula arranged according to polymer format rules in the entry box. Click OK.
|
| 4 |
The substance viewer appears. | |
| Refine results |
Follow these steps to create a more precisely defined polymer set. |
| Step |
Do this |
| 1 |
From the substance viewer, isolate polymers of interest by clicking Analyze or Refine  . |
| 2 |
The Analyze or Refine dialog box appears. Click Refine  . |
| 3 |
The Refine Substances dialog box appears. Click Chemical Structure  . |
| 4 |
The structure drawing window appears. To focus on polymers of interest, draw the structure of a unique fragment. Click Get Substances.
|
| 5 |
The Get Substances (Refine) dialog box appears. Select the substructure option. Click OK.
|
| 6 |
The substance viewer reappears.
