a local group called the root of the culture to go to poly siloxane, the manufacturing method and the use of water in bridge construction

摘要

this invention is a local group unsaturated radical is 250 c, the temperature and pressure of 900 ~ 1100 hpa in xylene and toluene organic solvent selected from among at least 80wt% can dissolve to the type (i) at least one unit: R1aR2 - aSiO 2 / 2: and (ii) at least. a unit: R1bR3 - bSiO 1 / 2, the type (III) of at least one of: O1 / 2R2SiOxYR SiO 2 / 2, and have a choice the type (IV) of at least one of: O1 / 1 / 2 2R2SiOxYR2SiO include polyvinyl siloxane to go on.;in this R1, r, a, b, x, and y is the definition of claim 1 holds.;but to go to poly siloxane, and (ii) (b 0.) the at least one word contains.;this invention is also to go to the siloxane of the manufacturing method and the bridge can be used in the material.
