| Abstract: | Stable polysiloxane latex were prepared by emulsion copolymerization of ocamethylcyclotetrasiloxane (Me-D4) and tetravinyltetramethylcyclotetrasiloxane (Vi-D4) using H 2SO 4 as initiator.Crosslinking reaction between vinyl groups on various prepolymers was carried out in the precence of free radical initiator.The distribution of Me-D4 and Vi-D4 residues in the copolymer chain was discussed based on the kinetics data of emulsion ring-opening copolymerization. |
