  • Plastics have had a significant influence on industrial, domestic and cultural aspects of everyday life in the twentieth and twenty-first centuries. They represent advances in technology, illustrated by the dramatic growth in number and type of information storage media available since the 1970s, credit and payment cards, medical applications and food containers which can be taken directly from freezer to microwave oven to dinner table. The development of plastics reflects economic history.

  • This book is the first in a new series devoted to synthetic works in the fields of ecology and evolution. These fields synthesis. Recent examples of synthetic activities include the establishment of the National Center for Ecological Analysis and Synthesis at the University of California Santa Barbara and Deep Green, a worldwide collaboration among angiosperm systematists to determine the phylogenetic structure of the flowering plants. In ecology some of the most important research challenges concern global climate change and the loss of diversity.

  • Petroleum products are everywhere around us. They appear in visible forms, such as gasoline, diesel, kerosene, and aircraft fuels, and in less visible forms over the entire spectrum of industry, such as automobile lubricants, greases, carbon black for truck tires, bitumen for road building, the waterproofing in house roofs, feedstock for petrochemicals, synthetic fibers, and plastics. Petroleum feedstock is used in the manufacture of white mineral oils in eye ointment, hair oils, cosmetics, petroleum solvents, and pest control sprays....

  • Number of the equipments used in everyday life remarkably increased after the invention of synthetic polymers, especially of styrene-butadiene rubber in 1930 and of PVC in 1936, and thanks to fast-developing polymer technologies. Polymers are light, cheap and ductile inert materials, which have good mechanical and thermal properties, suitable to use for various purposes and are highly resistant to corrosion. Thanks to such properties, they play an essential and ubiquitous role in many industrial fields.

  • New approaches to tailor-made cellulose/starch/lignin-synthetic polymer graft copolymers with precise control over molecular weight, degree of substitution, backbone-graft linkage, and the overall grafting process are being studied. Cross-linked graft copolymers with exactly defined polymer chain segments between crosslink points have been prepared. The graft copolymers exhibit a two-phase morphology and can function effectively as compatibilizers/interfacial agents to alloy cellulosic and lignocellulosic materials with synthetic polymers.

  • The most popular of the rigid reinforcements for printed wiring boards is woven E-glass (electrical-grade glass) fabric. These fabrics are constructed to meet weight, thickness, strength, and cost objectives. The woven fabric is used in many industries as reinforcements for thermoplastic and thermosetting plastic parts. Thermosetting laminates are particularly enhanced by the properties of the glass fabric.

  • Synthetic chemicals known as endocrine disruptors are an excellent example of emerging contaminants where the threats and consequences for water quality, human health, and the environment are still not fully understood. Endocrine disruptors – chemicals that can interfere with hormone action – have been identified among chemicals used in agriculture, industry, and households, and for personal care, including pesticides, disinfectants, plastic additives, and pharmaceuticals like birth control pills.
