Title:
膨張性シリコーン組成物及びその調製方法
Document Type and Number:
Japanese Patent JP5457034
Kind Code:
B2
Abstract:
A first silicone composition is consisting of:
a) a cross-linked silicone polymer network; and
b) a swelling amount of an alkyltrisiloxane where at least one alkyltrisiloxane (b) material results from the alkylation of a polyorganosiloxane having the formula (A):
MD H M(A)
where M = R A R B R C SiO 1/2 and D H = R D HSiO 2/2 , where R A , R B and R C are independently monovalent hydrocarbon radicals having from 1 to 60 carbon atoms; and R D is a monovalent hydrocarbon radical having from 1 to 60 carbon atoms or hydrogen. Said cross-linked silicon polymer network is swollen by said alkyltrisiloxane to form a first silicone composition, and said first silicone composition possesses a lower content in crosslinked silicone network (a) than a second silicone composition, consisting of said cross-linked silicon polymer network (a) and a swelling amount of a linear silicone fluid other than an alkyltrisiloxane (b), whereby second silicone composition and first silicone composition have identical viscosities.
