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 <IMAGE> 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. |
