The atoms within a polymer chain are bonded together by covalent bonds. The intermolecular forces between polymer chains are typically represented by van der waals forces and hydrogen bonds.</skos:definition> <metadata:prefixIRI>co:PMD_0000888</metadata:prefixIRI> <obo_purl:RO_0002353 rdf:resource="https://w3id.org/pmd/co/PMD_0010033"/> </owl:Class> <rdf:Description rdf:about="https://w3id.org/pmd/co/PMD_0050004"> <rdfs:subClassOf> <rdf:Description rdf:about="https://w3id.org/pmd/co/PMD_0000888"> <metadata_def:mappingSameURI rdf:resource="https://w3id.org/pmd/co/PMD_0000888"/> </rdf:Description> </rdfs:subClassOf> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/pmd/co/PMD_0090014"> <rdfs:subClassOf rdf:resource="https://w3id.org/pmd/co/PMD_0000888"/> </rdf:Description> </rdf:RDF>
