-
Paragraph 0113; 0114, (2018/02/03)
PROBLEM TO BE SOLVED: To provide a method that allows a high-purity bisphenol compound to be obtained in a crystal form with excellent handleability, conveniently and with high yields. SOLUTION: A method for producing a bisphenol compound comprises the step of precipitating a bisphenol compound represented by the formula (1) from a solvent containing at least one aliphatic alcohol solvent. [In formula (1), R1 is a C7-C19 alkyl group, R2 is a hydrogen atom or a C1-C19 alkyl group, R3-R6 independently represent a hydrogen atom or a methyl group].

, (2008/06/13)
Novel polycarbonates are provided which exhibit rubbery and elastomeric properties which are the polymerized reaction products of: (i) a carbonate precursor; and (ii) at least one dihydric phenol represented by the general formula STR1 wherein R is selected from straight chain alkyl radicals containing from 8 to about 30 carbon atoms; each R1 is independently selected from halogen monovalent hydrocarbon, and monovalent hydrocarbonoxy radicals; each R2 is independently selected from halogen, monovalent hydrocarbon, and monovalent hydrocarbonoxy radicals; and n and n' are independently selected from whole numbers having a value of from 0 to 4 inclusive.
