    Abstract: A process of forming a sustained-release pesticide coating, a process of forming a sustained-release pesticide capsule, and a sustained-release pesticide coating are disclosed. The process of forming the sustained-release pesticide coating includes depositing a first layer that includes a first pesticide onto a surface, and depositing a second layer that includes a photodegradable material onto the first layer. The process of forming the sustained-release pesticide coating also includes depositing a third layer that includes a second pesticide onto the second layer. The process of forming the sustained release pesticide capsule includes selecting a pesticide, selecting a photosensitive compound, and encapsulating the pesticide in a photosensitive capsule that includes a polymer formed from the photosensitive compound. The sustained-release pesticide coating includes a pesticide and a material having a photosensitive component. The material is in contact with the pesticide, and temporarily prevents the pesticide from contacting a surface.

    Abstract: An impact resistant polyhexahydrotriazine polymer, processes of forming an impact resistant polyhexahydrotriazine polymer, and an article of manufacture comprising an impact resistant polyhexahydrotriazine polymer are disclosed. The impact resistant polyhexahydrotriazine polymer includes at least one hexahydrotriazine group and at least one chain comprising an allylic portion and a styrenic portion. Variations in the chain control properties of the impact resistant polymer. The process of forming the impact resistant polyhexahydrotriazine polymer includes reactions between formaldehyde and at least two classes of monomer that form hexahydrotriazine groups and impact resistant chains. Adjusting relative monomer concentrations controls properties of the impact resistant polyhexahydrotriazine polymer. The article of manufacture contains a material that has an impact resistant polymer. Impact resistance of the impact resistant polyhexahydrotriazine polymer is dependent upon variation in relative amounts of monomers used in its synthesis.
