摘要：
This invention provides cycloaliphatic polyimide having the following formula (I): wherein 1 and n are integers from 4 to 7; m is an integer from 0 to 2; p is an integer from 1 to 8; polycyclic aliphatic compound R reprents C1-8 cycloalkyl, cycloalkenyl, cycloalkynyl, norbornenyl, decalinyl, adamantanyl, or cubanyl. That cycloaliphatic polyimide can be a through transparent film, their thermal stability is over 430° C. and dielectric constant is about 2.7.
