Functionalization of polypropylene in solution through grafting with monomethyl itaconate.
(SOCIEDAD CHILENA DE QUIMICA, 2000-06)
Polypropylene (PP) was functionalized in solution by grafting with monomethyl itaconate (MMI) by using xylene and decalin as solvents and 2,5-dimethyl-2,5-bis(tert-buthylperoxy)hexane (Lup. 101) as radical initiator. The ...
Compatibilizers based on polypropylene grafted with itaconic acid derivatives. Effect on polypropylene/polyethylene terephthalate blends
(SOC PLASTICS ENG INC, 2003-04)
New types of compatibilizers based on functionalized polypropylene (PP) were synthesized by radical melt grafting either with monomethyl itaconate or dimethyl itaconate. The effect of these new modified PP compounds were ...
Influence of grafted polypropylene on the mechanical properties of mineral-filled polypropylene composites
(JOHN WILEY & SONS INC, 2007-02-15)
The purpose of this work was to study how mineral fillers would behave in a polypropylene (PP) matrix when PP modified with maleic anhydride (MA) and/or itaconic acid (IA) was used as a coupling agent in the preparation ...
Efficiency of Different Chain-linking Agents in the Synthesis of Long-chain Branched Polypropylene. Molecular, Thermal and Rheological Characterization
(Taylor, 2017-09)
Long-chain branched polypropylenes were synthesized from a maleic anhydride grafted polypropylene (PPg). Different levels of branching were generated by reactive processing using four chain-linking agents: glycerol, ...

Evaluation of a plastic composite produced with residues of sugarcane bagasse and polypropylene without additives
(2015)
In this research the aim was produce and evaluate a plastic composite using recycled polypropylene (PP) and fibers from sugarcane bagasse residues (SC), without the use of additives. This analysis was based on laboratorial ...
Evaluation of a plastic composite produced with residues of sugarcane bagasse and polypropylene wihtout additives
(2015)
In this research the aim was produce and evaluate a plastic composite using recycled polypropylene (PP) and fibers from sugarcane bagasse residues (SC), without the use of additives. This analysis was based on laboratorial ...

Analysis of the interaction of lipases with polypropylene of different structure and polypropylene-modified glass surface
(Elsevier Science, 2007-02)
The hydrophobic/hydrophilic characteristics of the surface exposed by a lipase support conditions the amount of adsorbed protein, and probably also the conformation of the immobilized lipase. In reference to polypropylene ...
