Draw Polymers

Draw a Simple Polymer

  1. Draw the structure that forms the polymer.

  2. Click the Create Group tool on the toolbar and select the structure. Leave out the atoms that are to be replaced by * (star atoms).

  3. Choose the desired type from the drop-down list on the dialog.

  4. Set the polymer repeat pattern if necessary.

  5. Click OK.

Draw a Ladder-type Polymer

  1. Draw the structure that forms the polymer.

  2. Click the Create Group tool on the toolbar and select the structure. Leave out the atoms that are to be replaced by * (star atoms).

  3. Choose SRU polymer type from the drop-down list on the dialog.

  4. Set the polymer repeat pattern if necessary.

  5. Click OK.

To create a bracket that crosses two bonds, select two brackets which are each crossing a bond and click Merge Brackets in the context menu.

Draw a Copolymer

  1. Create the components to form the copolymer.

  2. Click the Create Group tool on the toolbar then select the components to be included.

  3. Choose type from the drop-down list on the dialog. The following types are available:

    • Copolymer (co)

    • Copolymer, alternating (alt)

    • Copolymer, block (blk)

    • Copolymer, statistical (stat)

  4. Click OK.

Change the Type of a Polymer

  1. Hover the mouse over the group.

  2. Select Edit Group from the context menu (right mouse click).

  3. Change the type of the polymer.

  4. Click OK.

Add a New Sub-polymer to a Copolymer

  1. Draw the sub-polymer outside of the bracket.

  2. Drag one part of the bracket to include the new sub-polymer.

Delete a Sub-group from a Copolymer

  1. Select the sub-polymer to be deleted.

  2. Press the Delete button on your or use the Erase tool.
