Multicomponent compounding of polypropylene
P. Järvelä,Pentti Järvelä +1 more
TL;DR: In this article, simultaneous compounding of polypropylene with several mineral fillers was investigated and the results showed that the best mechanical properties were attained by the simultaneous use of two or more fillers.

Melt rheological properties of polypropylene–maleated polypropylene blends. II. Dynamic viscoelastic properties
TL;DR: In this paper, the dynamic viscoelastic properties of polypropylene (PP)-maleated PP blends in the molten state have been investigated with a dynamic mechanical thermal analyzer (PL-DMTA MKII) at a frequency range (ω) of 0.6 * 10 -1 -3.14 * 10 2 rad s 1.

The three-fibre method for measuring glass fibre to resin bond strength
TL;DR: There are, however, some problems related to the method, including reproductivity of the test, determination of the degree of polymerization of the resin and the use of very thin fibres, but the method has been proved a very quick and relatively accurate indicator of the strengths of fibre/resin bonds.

Dynamic mechanical properties and morphology of polypropylene/maleated polypropylene blends
TL;DR: In this article, the dynamic mechanical properties of both homopolypropylene (PPVC)/maleated polypropylene(PP-g-MA) and ethylene-propylene block copolymer (PPSC)/female polymer (MPG) blends have been studied by using a dynamic mechanical thermal analyzer (PL-DMTA MKII) over a wide temperature range, covering a frequency zone from 0.3 to 30 Hz.

A comparison between apparent viscosity and dynamic complex viscosity for polypropylene/maleated polypropylene blends
TL;DR: In this paper, a series of blends of homopolypropylene with maleic anhydride polypropylene (PP-g-MA) and blends of an ethylene-propylene copolymer (PPSC) with PP g-MA were analyzed in terms of the Cox-Merz rule.
