Abstract: Disclosed are polymerizable compositions, methods, and articles and coatings related to multi-polymer networks wherein at least one of the polymer networks is based on particles. In an embodiment, the polymerizable compositions comprise at least two parts: 1) a polymer forming part comprising one or more compounds comprising a polymerizable group, wherein a composition consisting of the polymer forming part, if 90% or more polymerized, has a Tg of less than 25° C. and a prescribed volume average cross-link density at 100° C.; and 2) swellable particles comprising cross-links and having a Tg of less than 25° C. and a prescribed cross-link density. The swellable particles swell to a prescribed swelling ratio by mass from their non-swollen state if the swellable particles are swollen to equilibrium in a mixture consisting of the polymer forming part and the swellable particles.
