A); wherein PAamorp=peak area of the first elution, and PAtotal #191=total peak area of the polymers of the olefin-based polymer composition."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Determination of the amorphous content of polymers","description":"A method to determine the weight percent of an “amorphous” fraction in an olefin-based polymer composition, comprising one or more olefin-based polymers; said method comprising the following steps: a)","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11988650","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.
