If small amounts of local connectivity defects are introduced into a non-covalently crosslinked polymer network, there is evidence that the mobility of these defective building blocks is significantly accelerated. We intend to use both experiments and molecular simulations to derive a conceptual mechanism for this defect-assisted building block migration. For this purpose, we will develop a model-network platform with hetero-complementary interconnection of highly regular star-polymer building blocks to obtain truly defect-free networks as a reference state, and then purposely impart local connectivity flaws and track the motion of the building blocks that cause them.
