摘要：
Provided is an aliphatic polycarbonate resin having excellent water repellency and suitable for forming partitions in the production of wiring substrates.
The aliphatic polycarbonate resin for forming a partition contains a constituent unit represented by the formula (1) :
wherein R 1 , R 2 , R 3 , and R 4 are each independently a hydrogen atom, an alkyl group having one or more carbon atoms, an alkoxyalkyl group having two or more carbon atoms, an aryl group, or an aryloxyalkyl group; at least one of R 1 , R 2 , R 3 , and R 4 is an alkyl group having two or more carbon atoms, an alkoxyalkyl group having two or more carbon atoms, an aryl group, or an aryloxyalkyl group; and R 1 , R 2 , R 3 , and R 4 may be the same or different; and
the aliphatic polycarbonate resin has a contact angle against water of 75° or more.
