support.During the loading of titanium tetrachloride,an internal donor is incorporated to form
the main catalyst.Alkylaluminum cocatalysts and external donors are added during propylene
polymerization.
내부 및 외부 기증자 모두 촉매 활동을 향상시키고 제어하는 데 중요한 역할을합니다.
the isotacticity of polypropylene,among other properties.Compounds containing the 1,3-propanediol
dimethyl ether structural motif represent a novel class of donors.
These can achieve high activity and high isotacticity in polypropylene even without an external donor.
This significantly reduces thecomplexity of the polymerization system and holds substantial practical
value.

application characteristics.2-Isopropyl-2-isopentyl-1,3-propanediol dimethyl ether, also known as
2-isopropyl-2-isopentyl-1,3-dimethoxypropane, is a typical representatve of the diether internal
donor class:

European Patent EP0362705 (Montedison, 1989) indicates that using 2-isopropyl-2-isopentyl-
1,3-propanediol dimethyl ether as the internal donor achieves a catalytic activity of 3950 g
polypropylene per gram catalyst (3950 g PP/g cat) and an isotacticity of 98.5%.The specific
application scenarios and performance of the internal donor also depend significantly on the user’s
development efforts.
