Abstract

Etylenbasert kopolymer for ikke-tverrbundne vanntilførselsrør. Den etylenbaserte kopolymeren er framstilt ved bruk av en støttet hybrid-metallorganisk-katalysator og har en dimodal eller bred molekylvekt-fordeling. Den etylenbaserte kopolymeren har en molekyl-struktur med høy tetthet ved en lav molekylvekt, og har en lav tetthet med et høyt innhold av en komonomer ved en høy molekylvekt. Den etylenbaserte kopolymeren har en molekylvektfordeling på 5-30 og distribusjonen av kopolymerisering av etylen og et C a-olefin, er lokalisert i kjeder med høy molekylvekt. Følgelig har den etylenbaserte kopolymeren overlegen bearbeidbarhet, resistens mot sig ved høye temperaturer og innvendig trykk, samt spenningskorrosjon.
