“…Recently, enroll biodegradable organic materials to improve polymers properties has become the main concern for most researches [1,2,3] Polyurethane (PU) is high value polymer with a wide range of different applications [4]. The main applications of polyurethane are as insulation material (rigid foam) and in furniture (flexible foam) [5].…”

The needs to replace petroleum-based polyol by bio-source polyol in polyurethane industry were increased dramatically in the last few decades. The main obstacles associating with using bio-based polyol where the change in foam density and foam shrinkage. The reacting monomer was preheated to achieve a higher maximum reaction temperature that allows more setting of the cell structure and more stable foam matrix to overcome the vacuum forces and prevent density change and foam shrinkage. A simulation code for polyurethane reaction was used to find the optimum recipes with low catalyst loading to achieve a polyurethane foam with good properties.

“…Alternatively, there is a promising trend towards using polymer waste directly as an asphalt binder. One of the main issues of the polymer waste is that cannot degrade easily, causing, sometimes, serious environmental problems [7,8]. So, re-using the polymer waste in pavement construction, it would be advantageous in terms of both enhancing asphalt properties and reducing waste detrimental effect.…”

Plastics are durable and inexpensive, making the levels of their production high in relation to other materials. Further, the plastics have a slow degradation process under normal conditions, and as a result they have a long life-time. These two factors have led to increasing the plastic waste, affecting, adversely, inhabitants and environment. Re-using plastic waste as additives can be viewed as one of the promising approaches to tackle this issue and, equally, can be considered a cheap way of improving many engineering materials. In the current paper, the effect of adding polypropylene (PP) waste to asphalt mixture (asphalt and aggregate) was explored. The exploration was made first by determining the best asphalt content (without polypropylene) and then investigating the effect of different percentages of PP waste on the performance of this optimal mix. The results showed that 5.5% (by mass) gives a good balance among the properties (flow value, stability and bulk density). Further, the results indicated that the PP waste has improved most asphalt mixture characteristics where bulk density and flow values tests pointed that 9% of PP is the best concentration.

“…This decomposition produces hydrogen, carbon monoxide, carbon dioxide, and methane. The existence of carbon double bonds, as well as carbonyl groups, are one of the main reasons for disintegration which absorb the reaction energy from Ultraviolet light to form hydroperoxides by free radical mechanisms [2].…”

Miscible transparent blend consist of poly (methylmethacrylate) with cellulose acetate phthalate was prepared in order to get more transparent blend for ultraviolet rays. The blend was prepared by melt-blending and examined using UV-VIS spectroscopy. The structural, mechanical and thermal properties of selected samples were studied using X-ray diffraction, scanning electron microscopy, dynamic mechanical analysis, and thermos-gravimetric analysis. The UV-VIS spectrum exhibited the best blend ratio which has low absorbency to ultraviolet rays, On the other hand, high optical transparency within visible region. The results also showed that the blend has an amorphous structure as X-ray diffraction diffractogram. Moreover, thermal stability happened with the presence of cellulose acetate phthalate in the blend.
