Embodiment

[0139] Propylene polymers are prepared. Propylene polymer 1 (Table 1) used in the present invention was prepared by the following procedure.

[0140] polymerization

[0141] Polymer 1 was prepared in a pilot plant in which a loop reactor and a fluidized bed gas phase reactor were connected in series. Catalyst, cocatalyst and donor (donor, donor) are fed into the loop reactor. Before the solid polymer containing active catalyst enters the gas phase reactor, the reactor medium is flashed off.

[0142] A prepolymerized Ti supported catalyst (ZN104 from Basell) was used for the polymerization. The cocatalyst was triethylaluminum (TEAL 93% from SigmaAldrich), while the external donor was dicyclopentyldimethoxysilane (DCPDMS (99%) from WackerChemie). The TEAL / donor ratio (g / g) was 3 and the TEAL / C3 ratio was 0.23 g / kg.

[0143] The PP homopolymer matrix (polymer A) is prepared in the first stage (loop reactor) and the polymerization continues in the second stage (gas phase reacto...

Abstract

A composition comprising: (I) 60 to 92.5% by weight of a first component which is a polypropylene polymer comprising: a) 40 to 85% by weight having a A propylene polymer of melt flow rate (MFR2), and b) 15 wt% or more of at least one propylene-ethylene copolymer; and (II) 2.5 to 30 wt% of a second component comprising at least one ethylene- Alkyl (meth)acrylate polymer; and optionally (III) 5 to 25 wt% of at least one filler.

Description

technical field [0001] The present invention relates to a new material for injection molded articles exhibiting excellent scratch resistance and particularly low shrinkage anisotropy. More specifically, the present invention relates to a multicomponent polypropylene polymer to which at least one ethylenealkylacrylate polymer has been added. Background technique [0002] Due to its beneficial properties, polypropylene resin is widely used to form a variety of useful materials. The ability to tailor (tailor) the stiffness-toughness balance over a wide range makes polypropylene resins well suited for the production of tough and rigid structures such as body parts for automotive applications, which include exterior components such as bumpers (shock absorbers) , bumper), air dam (air suppressor, airdam) and internal components, such as instrument panels and airbag covers, etc. [0003] One disadvantage of polypropylene resins is that due to their semi-crystalline nature they un...
