Abstract: The invention provides compositions of matter, methods of their synthesis, and methods of their use in polymerization reactions. The compositions include polyfunctional initiators used to make star polymers when polymerized with monomers. The polyfunctional initiators are synthesized out of a multifunctional core with at least two functional groups and two or more initiator units bonded to the functional groups. The initiator units have two electron-withdrawing groups bonded to a central carbon atom and an azo group between the central carbon atom and the functional group. The polyfunctional initiators are particularly effective because when they decompose to form the radical core of a star polymer, the electron-withdrawing groups prevent the corresponding radical from forming any linear polymer contamination and only desired star polymers result.

Abstract: A process for preparing adenine by reacting an arylazomalononitrile with formic acid or its derivatives in the presence of ammonia and then subjecting the intermediate pyrimidine derivative to a reaction under catalytic reduction condition. Adenine can be prepared in high purity and high yields without isolating the intermediate pyrimidine derivative, when ammonia is removed before conducting the reaction under catalytic reduction condition. Also, the preparation of adenine in high purity and high yields can be more surely attained, when the arylazomalononitrile prepared under a specific condition is employed as a starting material or when Raney nickel is employed as a reduction catalyst in combination with active carbon. The produced adenine is effectively purified by separation of insoluble materials from an aqueous hot solution of adenine adjusted to pH 7.5 to 9.0 and formation of a mineral acid salt of adenine followed by decoloration by heating in the presence of active carbon.
