Polyolefin elastomers (POE) are thermoplastic elastomers synthesized through the in-situ polymerization of ethylene and \u03b1-olefins using metallocene catalysts. These polymers are characterized by their extremely low degree of crystallinity, low density, narrow molecular weight distribution, and low glass transition temperature. These properties grant them excellent compatibility with inorganic fillers and provide them with good resilience […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-227","post","type-post","status-publish","format-standard","hentry","category-blog"],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/posts\/227","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/comments?post=227"}],"version-history":[{"count":0,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/posts\/227\/revisions"}],"wp:attachment":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/media?parent=227"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/categories?post=227"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/tags?post=227"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
