Figure 5: Schematic representation of olefin polymerization with capsule 1 containing a radial initiator.
From: Safe storage of radical initiators within a polyaromatic nanocapsule

(a) Addition of the capsulated initiator to an organic solution of monomers. (b) Spontaneous release of the initiator from the capsule. (c) Polymerization of the monomers initiated by the initiator on photo or thermal stimuli.
