To provide bishydroxyarylsiloxane which has a structure in which a novel substituent is introduced between siloxane blocks, and in which physical properties of a copolymer can be adjusted when it is dispersed in the target copolymer, and a method of preparing the same.
The bishydroxyarylsiloxane is expressed by general formula (1) (wherein, R1 and R2 are independently C1 to C10 alkyl, C6 to C18 aryl, halogen, C1 to C10 aryl having C1 to C6 alkoxy or C6 to C18 aryl having C1 to C6 alkoxy, respectively; A is independently a single bond, -O-, -S-, C1 to C8 alkylene, aryl-substituted alkylene of C7 to C16, C1 to C8 heteroalkylene having -O- or -S- or C7 to C16 aryl-substituted heteroalkylene having -O- or -S-, respectively; Z is substituted or unsubstituted C4 to C18 alkylene group, substituted or unsubstituted C6 to C18 cycloalkylene or substituted or unsubstituted C10 to C18 arylene and, at this time, the substituent is C1 to C6 alkyl, C6 to C18 aryl or halogen; Y is independently halogen, C1 to C18 alkoxy, C1 to C10 alkyl or C6 to C18 aryl respectively; and n is independently an integer from 4 to 100 respectively).
