Title:
A HIGHLY TACTIC LADDER-LIKE POLYSILSEQUIOXANE AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/034161
Kind Code:
A1
Abstract:
A highly tactic ladder-like polysilsequioxane and preparation method thereof. The ladder-like polysilsequioxane is characterized by a regularity less than 1ppm, represented by baseline width (Δ) of RSiO3/2 absorption peak in 29Si-NMR. The preparation method thereof comprises the following steps: (1) reacting organic radical-bridged ladder polysiloxane of formula (II) with organic acyl dihalide to transfer arylenediimino bridge into silicon-halogen group, (2) mixing the product of step (1) with water and absorbent for hydrogen halide and carrying out hydrolysis reaction and hydrogen halide-removing reaction, (3) repeating step (1) and step (2).
