2-이소 프로필 -2- 이소 펜틸 -1,3- 프로판 디올 디메틸 에테르 (CAS # 129228-11-1 Ziegler-Natta 촉매에 대한 내부 전자 공여체)

◆간략한 소개

2-isopropyl-2-isopentyl-1,3-propanediol dimethyl ether (2-Isopropyl-2-isopentyl-1,3-dimethoxypropane)

is a high-performance internal electron donor used in modern MgCl₂-supported TiCl₄ Ziegler-Natta (ZN) catalysts

for polypropylene synthesis.

◆ Advantages over Legacy Donors:

• Replaces Phthalates: Non-phthalate structure addresses regulatory/environmental concerns (도달하다, RoHS 규제).

• High Thermal Stability: Maintains integrity during catalyst prep and polymerization.

• Improved Kinetics: Enables high catalyst activity and long-lasting productivity.

• Tailored PP Properties: Delivers PP with narrow molecular weight distribution (MWD) and consistent microstructure.

◆ 애플리케이션

• High-stiffness/high-flow injection molding PP

• Fiber-grade PP

• Biaxially oriented PP (BOPP) films

• Impact copolymer base resin

◆ Ziegler-Natta 촉매의 역할:

1. Stereoselectivity Control: Coordinates with the MgCl₂/TiCl₄ catalyst core to create highly stereospecific active sites, significantly

enhancing isotactic PP content (>98%). This reduces atactic polymer byproduct and improves product rigidity.

2. Active Site Templating:Its branched asymmetric structure (isopropyl + isopentyl groups) selectively stabilizes specific

crystalline faces of MgCl₂, promoting the formation of Ti active sites with optimal stereochemical control.

3. Hydrogen Response Modulator:Fine-tunes the catalyst’s sensitivity to hydrogen (molecular weight regulator),

enabling precise control over PP melt flow rates (MFR).

4. Performance Synergy:Works efficiently with external donors
