| 摘要 |
The invention relates to a novel thermoplastic monoorganopolysiloxane resin comprising units of the formula RSiO1.5 and R1R2R3SiO0.5 wherein R,R1,R2 and R3 are hydrogen, or organic groups which may be the same or different, at least 85% of the R groups in the RSiO1.5 being organic groups, and at least two of the groups R1, R2 and R3 in each R1R2R3SiO0.5 unit being organic groups, and in which the ratio RSiO1.5 units to R1R2R3SiO0.5 units is from 1:0.005 to 1:0.03 on a molar basis. Such resins are useful as electrical insulation material and as hold out agents for heat recoverable materials.
