Photocopier materials

Adhesive Transfer Processes. Many polymers, whether dehberately or accidentally, are adhesives, so that much of the adhesive industry can be regarded as a part of the mbber and plastics industry. However, there are several important material-transfer appHcations involving polymer products that are so critically dependent on controlled adhesion that they merit specific mention in that category. They include hot stamping foils, release coatings for pressure-sensitive adhesive products, photocopier materials, transfer coatings, and transfer printing of textiles. 

A crude approximation to computer-based systems can be achieved by considering tables of properties of plastics materials such as those published annually in the Modern Plastics Encyclopaedia. Since the tables are to be marked, the following exercise should be carried out on photocopies ... 

VOCs are emitted indoors by building materials (e.g., paints, pressed wood products, adhesives, etc.), equipment (photocopying machines, printers, etc.), cleaning products, stored fuels and automotive products, hobby supplies, and combustion activities (cooking, unvented space heating, tobacco smoking, indoor vehicle use).

The primary literature has grown so much in recent years that attempts have been made to reduce the volume. One such attempt is the Journal of Chemical Research, begun in 1977. The main section of this journal, called the Synopses , publishes synopses, which are essentially long abstracts, with references. The full texts of most of the papers are published only in microfiche and miniprint versions. For some years, the American Chemical Society journals, including J. Am. Chem. Soc. and J. Org. Chem., have provided supplementary material for some of their papers. This material is available from the Microforms and Back Issues Office at the ACS Washington office, either on microfiche or as a photocopy. These practices have not yet succeeded in substantially reducing the total volume of the world s primary chemical literature. 

Remember not to fill in the reagents or the mechanisms. For each reaction, jnst draw the starting material in front of the arrow and the prodncts after the arrow. Leave the space above the arrow empty. Yon will hll in the reagents when yon photocopy these pages ...
