Abstract

Oppfinnelsen er en forbedret lavdensitets etylenpolymerblanding og fremgangsmåte for fremstilling av denne. Polymerblandingen ifølge den foreliggende oppfinnelse inkluderer en hovedkomponent og en mindre komponent. Hovedkomponenten er en LDPE harpiks med en smelteindeks (I2) i området fra omtrent 0,01 dg/min til omtrent 100 dg/min, et Mw(abs)/Mw(GPC) forhold på omtrent 2,6 eller mindre, og en smeltestyrke på mindre enn (14,0 e(-1,05*log10(MI)))cN; den mindre komponent er en LDPE harpiks med en smelteindeks (I2) på mindre enn omtrent 5 dg/min, en molekylvektfordeling på mer enn omtrent 7, og et Mw(abs)/Mw(GPC) forhold på minst 2,7. Polymerblandingen ifølge den foreliggende oppfinnelse kan videre inkludere ytterligere komponenter. Videre inkluderer fri radikal initieringspolymerisasjonsprosessen ifølge den foreliggende oppfinnelse de følgende trinn: tilveiebringelse av etylen; og omsetning av etylenet i et reaktorsystem som inkluderer minst én rørreaktor og minst én autoklavreaktor, hvorved et høytrykksområde på fra omtrent 1260 kg/cm2 til omtrent 3870 kg/cm2, ved en reaktortemperatur på fra omtrent 190 ?C til omtrent 400 ?C, hvori etylenmatingen inn i reaktorene er oppdelt i flere etylenmatestrømmer, og minst én av etylenmatestrømmene inn i rørreaktoren hovedsakelig består av det ureagerte etylen. I tillegg kan den fri radikal initieringspolymerisasjonsprosess ifølge den foreliggende oppfinnelse videre inkludere trinnene med å tilveiebringe minst én eller flere komonomerer; og omsetning av etylenet og nevnte en eller flere komonomerer i reaktorsystemet ved et høytrykksområde på fra omtrent 1260 til 3870 kg/cm2, ved en reaktortemperatur på omtrent 190 ?C til omtrent 400 ?C.
