Chemical Modification of Polypropylene with Organo-functional Silanes
(University of Waterloo, 2015-01-05)Conventional polypropylene (PP) suffers at higher service temperatures and its poor melt strength limits its application in some processes. PP also lacks functional groups necessary for good adhesion to synthetic or natural ... -
Development and Characterization of Polypropylene, Cellulose Acetate, Magnesium Hydroxide Materials
(University of Waterloo, 2019-08-19)The urgency to develop and commercialize multi-component materials containing bio-based material is growing. Such materials can reduce the widespread dependence on petroleum and at the same time can reduce pollution while ... -
Effect of Thermal and Chemical Treatment of Soy Flour on Soy-Polypropylene Composite Properties
(University of Waterloo, 2012-05-02)Soy flour (SF), a by-product of the soybean oil extraction processing, was investigated for its application in soy-polypropylene composites for interior automotive applications. The emphasis of this work was the understanding ... -
Highly Filled, Durable, and Sustainable Wood-Plastic Composites from Recycled Thermoplastics
(University of Waterloo, 2022-09-26)The increasing concern for environmental sustainability and the accumulation of solid waste (e.g. single-use plastics) has led to an increased interest in the utilization of renewable feedstocks and recycling of plastics ... -
Mechanical Behaviour, Water Absorption and Morphology of Wheat Straw, Talc, Mica and Wollastonite filled Polypropylene Composites
(University of Waterloo, 2012-05-23)Polypropylene continues to be the mainstream choice thermoplastic for automotive applications. In many applications PP is filled with mineral fillers for improvement of properties. Biobased natural fillers or fibres are ... -
Propylene Polymerization Using 4th Generation Ziegler-Natta Catalysts: Polymerization Kinetics and Polymer Microstructural Investigation
(University of Waterloo, 2011-08-11)A systematic study of propylene polymerization using a 4th generation Ziegler-Natta catalyst is presented in this thesis. The apparent kinetic rate constants for propylene polymerization were estimated in the presence and ... -
Rheological Modification of Polypropylene by Incorporation of Long Chain Branches Using UV Radiation
(University of Waterloo, 2014-11-21)Modification of polypropylene (PP) is important as it aims at changing the molecular structure of PP and synthesizing different grades of PP for different processing applications. These changes include narrowing of the ... -
Wheat Straw-Clay-Polypropylene Hybrid Composites
(University of Waterloo, 2009-09-23)The preparation of polymeric hybrid composite consisting of organic and inorganic fillers is of interest for industries like automotive, construction and packaging. In order to understand and predict the physical and ...
