The blend includes from 40 wt % to 95 wt % of the ethylene acid copolymer, from 5 to 50 wt % of the aliphatic, mono-functional organic acid, based on the total weight of the blend. The ethylene acid copolymer is the polymerized reaction product of ethylene, from 1 to 25 wt % of monocarboxylic acid and from 1 to 40 wt % of alkyl acrylate, based on the total weight of the monomers present in the ethylene acid copolymer. The aliphatic, mono-functional organic acid has fewer than 36 carbon atoms. In various embodiments, at least 70 mole % of total acid units are neutralized with both a trivalent cation and either a mono- or di-valent cation.Type: GrantFiled: July 15, 2019Date of Patent: March 12, 2024Assignee: Dow Global Technologies LLCInventor: Xian Jiang

Patent number: 11926735Abstract: The invention relates to cyanate ester resin blends containing resveratrol-based cyanate esters. At room temperature, the cyanate ester resin blend offers improved processability by remaining a liquid or forming a solid that melts at less than 70° C. The cyanate ester resin blend includes a resveratrol-based cyanate ester and a flexible cyanate ester having a configuration different than that of the resveratrol-based cyanate ester, where the resveratrol-based cyanate ester is no more than 80% of the total mass of the cyanate esters in the cyanate ester resin blend. A composite product can include the cyanate ester resin blend and a support material. When making the composite product, the support material is combined with the cyanate resin blend and cured at temperatures ranging from about 100° C. to about 300° C.Type: GrantFiled: November 10, 2021Date of Patent: March 12, 2024Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Benjamin G.
