A mononuclear star-branched polymer dielectric material having a repeat unit of the formula (I):n nA-B n (I)n nwherein, A represents a multifunctional center having a functionality and a functional group with “n” arms; n is an integer greater than 2. B represents a hydrolyzed or partially hydrolyzed compound of the formula (II):n n nwherein, X represents H or CH 3 ; R represents H, alkyl or is selected from a group consisting of acetoxyl, t-butyl, t-butyldimethyl silyl, acid labile groups and acid stable groups; “a” is an integer from 1 to 5; y and z are molar ratio and are the numbers satisfying y+z=1, 0<y≦1 and 0≦z<1. |
