In recent years, there have been many patent applications for various structural forms of non-pneumatic tires, such as a technology of supporting a load of a tire by a plurality of support members using a plurality of layers of staples, a technology of forming a carcass made of an elastic material, a circumferentially extending crown and an extending sidewall, a technology of forming a honeycomb-shaped buffer portion to realize a buffer technology pressure non-pneumatic tire, and a technology of forming a web-shaped spoke structure to open in a tire rotation direction to construct a non-pneumatic tire, and a recently disclosed non-pneumatic tire according to korean patent application, which is published as a chinese patent application, with patent application publication No. CN111137069A, in which web-shaped spokes form closed web-shaped spokes along the tire rotation direction, and the patent technology is to form an element structure at connection portions inside the web-shaped spokes, thereby solving better problems of flexibly absorbing various impact forces and supporting the load by the non-pneumatic tire.

The molecular weight distribution is generally referred to as the ratio of weight average molecular weight to number average molecular weight. This value varies between 2 and 5, depending on the normal and highly branched structure. Because of the branched bond, the ethylene propylene diene rubber containing DCPD has wider molecular weight distribution.

With increasing molecular weight distribution, the positive effects are: increased mixing and milling processability. However, a narrower molecular weight distribution can improve the vulcanization speed, the vulcanization state and the injection molding behavior.
