Musiyano we viscosity wePDMS (polydimethylsiloxane, inozivikanwawo se dimethyl silicone mafuta) inonyanya kukonzerwa nedhigirii repolymerization, uye zvakare inokanganiswa zvishoma neiyo molecular chimiro (senge mhando yemapoka ekupedzisira). Iyi inotevera tsananguro yakadzama kubva pakuona kwechimiro chemakemikari:
Iyo dhigirii yepolymerization ndiyo yakakosha chinhu chinotaridza viscosity yePDMS.
Chimiro cheMolecular of PDMS ndecheni yemutsara-senge, nechikamu chinodzokorora chiri -Si(CH₃)₂-O-, uye chimiro chayo chese chinogona kutaurwa se: (CH₃)₃SiO{4}}[Si(CH₃)₂ -₂{5}}₂ -₂{5}} {} {} } {} } {} (CH₃) ₃ apo n ndiyo dhigirii repolymerization (nhamba yekudzokorora zvikamu).
Iyo yakakwira dhigirii yepolymerization (yakakura iyo n) : iyo yakareba iyo molecular cheni, iyo inosimba iyo van der Waals masimba (kunyanya kupararira masimba) pakati pemamorekuru, uye inokwirisa iyo entanglement dhigirii pakati pemaketani, zvichikonzera kuderera kwemvura uye kuwedzera viscosity. Iyo yakaderera dhigirii yepolymerization (iyo diki n), iyo ipfupi ye molecular cheni, iyo isina simba iyo intermolecular masimba, kushoma entanglement, zviri nani kuyerera, uye kudzikisa viscosity.
Semuyenzaniso, dhigirii repolymerization yepasi-viscosity PDMS (senge 100 mm²/s) kazhinji ishoma (n ingangoita makumi akati wandei). Kuwanda kwepolymerization kwepamusoro-viscosity PDMS (se100,000 mm²/s) inogona kusvika kumazana kana kunyange zviuru.
