(Q119896085)
Statements
Metaclass that covers polymers, i.e. mixtures of macromolecules (chemical entities). When describing a particular macromolecule, 'type of chemical entity' (Q113145171) should be used, while plastics (materials made of a specific polymer) should be described as a subclass of 'plastic' (Q11474) and resins (mixtures of prepolymers) as a subclass of 'resin' (Q145205), and this metaclass should not be applied to any of them.
