A vinyl polymer having a 9,10-substituted anthracene structure which is a stable structure with a high solid quantum efficiency is obtained from a vinyl monomer having a group derived from the structure of formula (1) wherein n<SUB>1 </SUB>is an integer of 1 to 3, each of X<SUB>1</SUB>, X<SUB>2</SUB>, X<SUB>3 </SUB>and X<SUB>4 </SUB>is a substituent group, k<SUB>1 </SUB>and k<SUB>4 </SUB>are integers of 0 to 5, and k<SUB>2 </SUB>and k<SUB>3 </SUB>are integers of 0 to 4. An organic EL device comprising an organic layer containing the vinyl polymer becomes a molecule dispersed type organic EL device featuring a high efficiency and a long life.
