Ethylene copolymers and process for the production thereof

Abstract

The present invention relates to an ethylene copolymer comprising: (iv) ≥78.0 and ≤99.9 mol % of recurring units derived from ethylene; (v) ≥0.10 and ≤20.0 mol % of a recurring units derived from a comonomer A according to formula (I) wherein R1 is a moiety comprising 1-30 carbon atoms; R2 is selected from —H or —CH; R3 is selected from —O—, —(CO)—(NH)— or —(CO)—O—; n=0 or 1; and m≥1 and ≤10; and (vi) ≥0.01 and ≤2.00 mol % of a recurring units derived from a comonomer B according to formula (II) wherein R1 is a moiety comprising 1-30 carbon atoms; each R2 may individually be selected from —H or —CH; each of R3 is individually selected from —O—, —(CO)—(NH)— or —(CO)—O—; n=0 or 1; p=0 or 1; and m≥1 and ≤10; the mol % of each of (i), (ii) and (iii) being related to the sum of the mol % of (i), (ii) and (iii), the sum of the mol % of (i), (ii) and (iii) adding up to 100 mol %. Such 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 and contact angle, combined with a desired melt mass-flow rate.
