polymer
Let an agent explain polymers and their structure-property relationships, identify polymer types and applications, and address recycling, safety and environmental questions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain polymers and their structure-property relationships, identify polymer types and applications, and address recycling, safety and environmental questions.
A substance composed of very large molecules made of many repeating subunits, including natural polymers such as proteins, cellulose, rubber and DNA and synthetic polymers such as polyethylene, nylon and silicones; polymers form plastics, fibres, elastomers, coatings and gels, and their production, use and disposal raise environmental issues.
What it is for: Materials, biology and industry.
It can be explain polymer structure and properties; identify polymer types; support material selection; explain recycling and environmental issues.
