Term: polymer–polymer complex
https://doi.org/10.1351/goldbook.P04743

Definition:
Complex, at least two components of which are different polymers.

Notes:
0) A complex is a molecular entity formed from two or more components that can be ionic or uncharged.
1) Although the intrinsic @BT07001@ between the individual interacting sites giving rise to the complex is weaker than a @C01384@, the total @BT07001@ for any single molecule may exceed the energy of a single @C01384@.
2) The properties of a complex defined here differ from those given elsewhere because, owing to the repeating nature of a @M03667@, many interacting sites may be present, which together will provide stronger bonding than a single @C01384@.
