Effect of phthalocyanine blue pigment on mechanical and thermal properties of polypropylene copolymers
Abstract
<p>Samples of two commercial polypropylene copolymers, one a random copolymer and the other a block copolymer, containing 0-8wt.% phthalocyanine blue pigment were injection moulded using mould temperatures of 40°C to 80°C. Dynamic Mechanical Thermal Analysis (DMTA) and Differential Scanning Calorimeter (DSC) analysis showed the presence of different crystalline phases in each polymer, the amount of each phase changing with increasing pigment loading. With these changes in the crystalline phases there was a progressive increase in tensile modulus, storage modulus (E′) and glass transition temperature (T<sub>g</sub>) for both copolymers. Impact performance of both pigmented copolymers decreased with an increase in pigment loading and mould temperature, with the most dramatic result shown for the random copolymer. These impact results were mirrored by the fall in loss modulii of both copolymers with increasing pigment loading.</p>
