Properties of a substance specific to it being a polymer. Properties of a substance specific to it being a polymer. If the element is present, it must have either a @value, an @id, or extensions A business idenfier for this polymer, but typically this is handled by a SubstanceDefinition identifier. Overall type of the polymer. Polymer geometry, e.g. linear, branched, cross-linked, network or dendritic. Descrtibes the copolymer sequence type (polymer connectivity). Todo - this is intended to connect to a repeating full modification structure, also used by Protein and Nucleic Acid . String is just a placeholder. Todo. Specifies and quantifies the repeated units and their configuration. Properties of a substance specific to it being a polymer. Captures the type of ratio to the entire polymer, e.g. Monomer/Polymer ratio, SRU/Polymer Ratio. The starting materials - monomer(s) used in the synthesis of the polymer. Properties of a substance specific to it being a polymer. The type of substance for this starting material. Substance high level category, e.g. chemical substance. Used to specify whether the attribute described is a defining element for the unique identification of the polymer. A percentage. Properties of a substance specific to it being a polymer. A representation of an (average) molecular formula from a polymer. How the quantitative amount of Structural Repeat Units is captured (e.g. Exact, Numeric, Average). An SRU - Structural Repeat Unit. Properties of a substance specific to it being a polymer. Structural repeat units are essential elements for defining polymers. The orientation of the polymerisation, e.g. head-tail, head-head, random. Number of repeats of this unit. Applies to homopolymer and block co-polymers where the degree of polymerisation within a block can be described. A graphical structure for this SRU. Properties of a substance specific to it being a polymer. The type of the degree of polymerisation shall be described, e.g. SRU/Polymer Ratio. An average amount of polymerisation. A low expected limit of the amount. A high expected limit of the amount. Properties of a substance specific to it being a polymer. The type of structure (e.g. Full, Partial, Representative). The structural representation as text string in a standard format e.g. InChI, SMILES, MOLFILE, CDX, SDF, PDB, mmCIF. The format of the representation e.g. InChI, SMILES, MOLFILE, CDX, SDF, PDB, mmCIF. An attached file with the structural representation.
