Polymer
In PoLyInfo, information on Polymer is caught at three following levels and arranged.
  • 1. Constitutional repeating unit (CRU) / Constituional unit(CU)
  • Level by which Polymer as molecule is discerned from the unit of chemical structure that composes it. It is especially said, "Constitutional repeating unit (CRU)" for a regular polymer.
  • 2. Polymer chain / Polymer molecule
  • Level by which one Polymer molecule is discerned as a connected body of a lot of constitutional units (CU) /constituional repeating units (CRU).
  • 3. Polymeric material
  • Level of material as set of Polymer chain/Polymer molecule.

    It uses when saying ..word "Polymer".. the whole in the homepage and Help of PoLyInfo these, and the corresponding term of 1.-3.
  • when of each is distinguished is used. Moreover, 2. and 3. are matched in 1. and the meaning to make it compare, and it is called, "Polymer sample".

Constitutional repeating unit (CRU) / Constitutional unit (CU)
  • constitutional repeating unit (CRU) (in polymers)
    The smallest constitutional unit the repetition of which constitutes a regular macromolecule, a regular oligomer molecule, a regular block or a regular chain. 1996, 68, 2291

  • constitutional unit
    An atom or group of atoms (with pendant atoms or groups, if any) comprising a part of the essential structure of a macromolecule, an oligomer molecule, a block or a chain.  

  • In PoLyInfo, the unit of the chemical structure that can describe Polymer chain is called "Constitutional repeating unit/constituional unit".

    "Constitutional repeating unit (CRU)" means a minimum unit of chemical structures that can describe the polymer chain that excludes the end radical and the joint part by the repetition in the word used only in case of a regular linear polymer.

    "Constitutional unit (CU)" means the unit of a constant chemical structure that can describe polymer chain/polymer molecule by the repetition and the combination in the word used regardless of the kind of Polymer, which contain the end radical and the joint part.

    Constitutional repeating unit (CRU) / Constituional unit (CU) is targeted in discernment and identification in the polymer dictionary in PoLyInfo. Moreover, it expresses it bringing these together in the word of "Constitutional unit" or "CU".

Polymer dictionary


Polymer dictionary
Polymer dictionary is a compound registry system only for polymer developed by PoLyInfo. Identification of the chemical structure is done based on the chemical structure of constituional repeating unit (CRU).
It is identified, by the function of the polymer dictionary based on the chemical structure of the constituional unit, and an original identification number (Polymer ID) is given to Polymer collected in PoLyInfo.
The following item that can be decided from the chemical structure of the constituional unit is collected in the polymer dictionary.

The following item of each sample that adopts data used to identify the polymer is collected. Moreover, information on the monomers that are the raw material of the polymer is related to the polymer dictionary, and collected in monomer information.
  • Reference document concerning polymer dictionary
    The 21th informationization study round-table discussion lecture summary collection, 82(1998)

  • Reference document concerning whole of PoLyInfo
    Informatics symposium lecture thesis collection in 2000, 41(2000)

Compound registry system
Compound registry system is a computer system that identifies the compound.
Centering on the chemical structure data expressed with the form of computer readable, data, such as various kinds of names and a molecular formula, is matched and recorded. Since discernment and identification of the data recorded are done based on chemical structure and it is managed unitary, it can prevent duplicated registration of the same compound.

Moreover, the user can search the specified compound from either the name or the chemical structure by using the compound registry system.
There are typical compound registry systems by Chemical Abstracts Service(CAS) and a Japanese compound dictionary system by JST, etc.


[CU, Sample]


Polymer ID
Unique management number given after polymer is identified by function of polymer dictionary based on chemical structure of constituional unit. Polymer ID is made in the form of abbreviation P that show Polymer + of six digits numerical value (ex. P150045).


Sample ID
Data identification number of each Polymer sample. This number is truly unique in PoLyInfo.The number is shown as a reference number and a polymer sequence number in the reference.


Polymer names
Because data is arranged at constituional unit (CU) level and polymeric material (sample) level in PoLyInfo, the names are shown as the CU name and the material name, and the following Polymer names of the kind of are collected. The polymers are named in accordance with the IUPAC nomenclature rules or recommendations.
