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.
