Organosiloxanes waa fasal sare {{0} xeryahooda molecular oo leh Si{1} ○ -Si bonds sida silsiladda ugu weyn iyo kooxaha organic si toos ah ugu xidhan atamka silikoon. Nidaamkooda guud waa sida soo socota:(R. sio-m /2). Halkan, R waxay u taagan tahay kooxaha organic sida methyl, phenyl, vinyl, iwm., iyo "waa heerka polymerization. Sida xeryahooda polymer caadiga ah, polysiloxanes organic sidoo kale waxaa loo kala saari karaa toosan, laamosan -silsilad, iskutallaab{11}isku xiran{11}iyo noocyo kale iyadoo loo eegayo kala duwanaanshaha qaabdhismeedka silsiladda.
Habka diyaarinta ee polysiloxanes organic waxaa qiyaas ahaan loo qaybin karaa laba qaybood oo waaweyn: polycondensation iyo giraanta -openingpolymerisation.Polycondensation waa fal-celin kiimikaad kaas oo monomers leh laba ama in ka badan oo kooxeed ay iskaga falceliyaan midba midka kale si ay u sameeyaan {{0} xeryahooda molecular sare, iyagoo sidoo kale soo saaraya unugyo yaryar. Giraanta -polymerization furitaanka waa nooc ka mid ah falcelinta polymerization-ka, taasoo la macno ah in aan -molecule by- alaab yar la sii dayn inta lagu jiro habka falcelinta. Sidaa darteed, isku-dhafka kiimikada ee polymer-ka dheeriga ah wuxuu la mid yahay kan monomer-ka bilawga ah.
