Ine mhando dzakawanda, dzinosanganisira aliphatic thiols, xanthate disulfide, polyphenols, sulfur, halides uye nitroso compounds, uye inoshandiswa zvakanyanya mu free radical polymerization reactions.

Molecular weight regulator inoreva kuwedzerwa kwezvinhu zvishoma zvine chain transfer constant yakakura mu polymerization system. Nekuti kugona kwe chain transfer kwakanyanya, kuwedzera kushoma chete kunogona kuderedza zvakanyanya molecular weight, asiwo nekugadzirisa dosage kuti idzore molecular weight, saka rudzi urwu rwe chain transfer agent inonziwo molecular weight regulator. Semuenzaniso, dodecyl thiols dzinowanzo shandiswa se molecular weight regulators mukugadzirwa kwe acrylic fiber. Molecular weight regulator inoreva chinhu chinogona kudzora molecular weight ye polymer uye kuderedza chain branching ye polymer. Hunhu hwayo ndehwekuti chain transfer constant yakakura kwazvo, saka diki inogona kuderedza zvinobudirira molecular weight ye polymer, izvo zvinobatsira mushure mekugadzirisa nekushandisa polymer. Regulator muchidimbu, inozivikanwawo se polymerization regulator.
shandisa
Mu emulsion polymerization yerabha yakagadzirwa, kazhinji unoshandisa aliphatic thiols (yakadai sedodecarbothiol,CH3 (CH2) 11SH) uye disulphide diisopropyl xanthogenate (ndiko kuti, regulator butyl)C8H14O2S4, kunyanya aliphatic thiols, uye inokurumidza kuita reaction; Mu olefin coordination polymerization, hydrogen inoshandiswa se molecular weight regulator.

B. Chigadzirwa ichi chinogona kushandiswa, 25KG, 200KG, 1000KG, bharero.
C. Chengeta yakavharwa munzvimbo inotonhorera, yakaoma uye ine mhepo mukati. Midziyo inofanira kuvharwa zvakasimba mushure mekushandisa kwega kwega usati washandisa.
D. Chigadzirwa ichi chinofanira kuvharwa zvakanaka panguva yekufambisa kudzivirira hunyoro, alkali yakasimba uye acid, mvura nezvimwe tsvina kuti zvisasanganiswe.
