NOVELTY - A moisture-curable modified polysiloxane (I), is new. USE - New moisture-curable modified polysiloxane for preparation of room temperature vulcanized silicone rubber. ADVANTAGE - The modified polysiloxane has single linear structure and stable viscosity before and after curing, and can be moisture-cured at room temperature and solve the problem of viscosity peak in curing process of existing polysiloxane, and provides vulcanized silicone rubber with excellent performance and storage stability. DETAILED DESCRIPTION - A moisture-curable modified polysiloxane of formula (I), is new. R1 = aryl, alkyl or arylalkyl; R2 = 1-8C aliphatic hydrocarbyl; x,y = 2-5; n = more than 1; z = 1-8;and j = 0-2. INDEPENDENT CLAIMS are included for the following: (1) preparation of the compound (I); and (2) use of compound (I) in preparation of room temperature vulcanized silicone rubber.
