TL;DR: In this article, a copolymer with high fluidity and improved properties in terms of hardness, flexural strength, tensile strength, and the like has been proposed, as the contents and types of unsaturated functional groups therein are adjusted.

TL;DR: In this paper, a polypropylene-based composite consisting of polyethylene and an olefin-based copolymer satisfying the following conditions: (1) density (d) is 0.85-0.89 g/cc; (2) melt index (MI, 190°C, 2.16 kg load condition) is 15-100 g/10min; (3) the number of unsaturated functional groups (total V) per 1,000 carbon atoms was 0.8-1.6 or less; and (4) the total

TL;DR: In this article, the authors presented an ethylene/alpha-olefin copolymer which exhibits desirable long-term properties, showing little changes in terms of color, molecular weight, and viscosity even after being stored at high temperatures for a long time.

TL;DR: In this paper, the authors presented an ethylene/alpha-olefin copolymer and a method for preparing the same, the copolymics having a narrow molecular weight distribution with low density and ultra-low molecular weight, and having a minimum number of unsaturated functional groups and a particularly low content of vinylidene among the unsaturated groups.

TL;DR: In this paper, an olefin-based copolymer with high flowability and high hardness has been proposed, which can exhibit improved physical properties such as hardness, flexural strength and tensile strength.
