Process for preparing star compounds |
| abstract |
A process for preparing a three-branched or four-branched star compound comprising polymerizing an olefin compound represented by the formulan n wherein A is a single bond or phenylene group, and R 3 is a hydrogen atom or methyl group and R 4 is a monovalent organic group when A is a single bond, or R 3 is a hydrogen atom and R 4 is an alkyl group when A is a phenylene group, using as an initiator the adduct of a polyfunctional alkenyl ether represented by the formula (I)n wherein R 1 is a hydrogen atom or methyl group, n is an integer of 3 or 4, and R 2 is a trivalent organic group when n is 3 or a tetravelent organic group when n is 4 with a cation-donating compound. |
