Abstract
Official abstract text for this publication.
An impact resistant polyhexahydrotriazine polymer, a process for forming an impact resistant polyhexahydrotriazine polymer, and an article of manufacture comprising an impact resistant material containing 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.
First claim
Opening claim text (preview).
What is claimed is: 1. An impact resistant polymer, comprising: at least one hexahydrotriazine group, wherein the number of hexahydrotriazine groups formed affects impact resistance of the impact resistant polymer; and at least one chain comprising an allylic portion and a styrenic portion. 2. The impact resistant polymer of claim 1 , wherein adjusting the amount of butadiene controls the degree of cross-linking in the impact resistant polymer. 3. The impact resistant polymer of claim 2 , wherein the degree of cross-linking affects impact resistance of the impact resistant polymer. 4. The impact resistant polymer of claim 1 , wherein the at least one chain further comprises a flame retardant portion. 5. The impact resistant polymer of claim 4 , wherein the flame retardant portion is a phosphorus-containing portion. 6. The impact resistant polymer of claim 1 , wherein the styrenic portion is a polyaminostyrene portion.
