Cured films containing the polymer can exhibit at least one of the following properties: Tg from 160° C. to 180° C., a dielectric constant below 2.7 with frequency independence, and a maximum moisture absorption of less than 0.17 wt %. Accordingly, the polymer is especially useful, for example, in interlayer dielectrics and in die-attach adhesives."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polymeric compositions comprising per(phenylethynyl) arene derivatives","description":"A polymeric composition comprising a first polymer chosen from a poly(arylene ether) polymer including polymer repeat units of the following structure: —(O—Ar1—O—Ar2—O—)m—(—O—Ar3—O—Ar4—O)n- where Ar1,","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8502401","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
