| titleOfInvention | Ethylene-propylene random copolymer with low dissolution, low melting point, narrow molecular weight distribution and stable thermal oxygen, and preparation method and application thereof |
| abstract | The invention relates to the field of polyolefin, in particular to an ethylene-propylene random copolymer with low dissolution, low melting point, narrow molecular weight distribution and stable thermal oxidation, a preparation method and application thereof, wherein the ethylene content of the ethylene-propylene random copolymer is 0.1-8 wt%; a xylene solubles content at room temperature of less than 10 wt.%; the melting point is lower than 160 ℃; a rheological polydispersity index PI of less than 3.5; the melt index of the original granules is more than or equal to 1.0g/10min, the MFR change rate of the secondary granulated granules is lower than 18%, and the MFR change rate of the tertiary granulated granules is lower than 60%; wherein the room temperature xylene soluble content y and the ethylene content x of the ethylene-propylene random copolymer satisfy the following relational expression: y-ax-b, a is 1.6-1.9, and b is 0.006-0.008. The ethylene-propylene random copolymer has the characteristics of low dissolved matter, low melting point, narrow molecular weight distribution and stable thermal oxygen, and is suitable for films and transparent injection products. |
