Polymer Database (PoLyInfo)
Polymer Database "PoLyInfo" systematically provides various data required for polymeric material design. The main data source is academic literature on polymers. Information on polymers including properties, chemical structures, IUPAC names, processing methods of measured samples, measurement conditions, used monomers and polymerization methods are stored in a object database. About 100 types of properties including thermal, electrical and mechanical properties are covered. Homopolymers, copolymers, furthermore polymer blends, composites and compounds that consist of homopolymers and copolymers are open to the public.

Database
Polymer Search
Polymer Search is done by specifying the polymer name, type, chemical formula, material type, properties and reference publication. There are "Basic" (simple condition setting) and "Advanced" (detailed condition setting) searches, and furthermore "Text" (text search) that searches all display contents.
Polymer Structure Search
A search can be done by specifying the type and quantity of an atom group included in the constitutional unit of the polymer.
Easy Browse
The user can search from the "Plotted data".
Monomer Search
Monomer Search is done by specifying the monomer name, registry No., class, molecular formula and molecular weight.
NMR Database
1H, 13C NMR spectra of 154 samples are provided with assignment data.
