Abstract
The present invention relates to an ethylene copolymer obtained by radical polymerisation through a high-pressure process comprising (i) ≥78.0 and ≤99.99 mole % of recurring units derived from ethylene; (it) ≥0.01 and ≤22.0 mole % of recurring units derived from comonomer A according to Formula (I), wherein R1 is composed of a saturated aliphatic moiety comprising 5-40 carbon atoms or R1 is composed of a saturated aliphatic moiety and consists of hydrogen atoms and 5-40 carbon atoms; R2 is selected from —H or —CH; R3 is selected from —O—, —(CO)—(NH)— or —(CO)—O—; n=0 or 1 The ethylene copolymers have a reduced peak melting temperature and reduced enthalpy of fusion, indicating that these ethylene copolymers have a reduced degree of crystallinity and improved clarity, combined with a desired melt mass-flow rate.
