a resin having a polymeric structure; especially a resin in the raw state; used chiefly in plastics

Any complex organic liquid or solid formed from simpler molecules by polymerization or condensation; any of various chemically modified natural resins.

A resin made through more complex laboratory or factory processes, usually from petroleum derivatives. Such plastics can be designed to suit many requirements (including esthetic ones). Examples used in penmaking include acrylic and ABS.

Complex, substantially amorphous organic semi-solid or solid materials built up by chemical reaction of simple molecules.

Resins prepared by chemical means.

A solid or liquid organic compound made by polymerization, the material of which a plastic is made, including epoxy resin, acrylic resin, and many other polymers; chemical compounds react to form synthetic resins.
