Self-adhering (tacky) materials or pressure-sensitive adhesives (PSA) form an essential part of our everyday lives, with new applications of PSAs arising all the time across various industries. The vast majority of existing PSAs are hydrophobic rubber-like polymers, which means they don't mix well with polar molecules. However, it is precisely that quality that would be of greatest practical use in contemporary industry and medicine.This book describes innovative hydrophilic PSAs based on stoichiometric hydrogen bonded complexes of long-chain polymers (with repeating electron-donating functional groups) with complementary telechelic oligomers (with proton-donating terminal groups).These types of adhesives can be easily produced by simple mixing of parent polymers and oligomers in solutions or in melts. Unlike conventional hydrophobic adhesives, these hydrophilic adhesives are miscible with a range of chemical substances that have hydrogen bonding or ionic functional groups in their molecules. This includes numerous drugs, polyelectrolytes, electroconducting or physiologically active compounds, proteins, etc.The book shows the molecular design principles and distinctive characteristic features of various functional adhesive products based on innovative tacky polymer composites, such as:'smart' thermo-switchable adhesives adhering towards the substrates of different polarity and hardnessmussel-inspired adhesives functioning in aqueous mediatransdermal patches for enhanced drug deliverytooth whitening strips with tailored adhesion towards dental tissuesthe lack of adhesion to mucosal membranes in oral cavitymany other advanced products for medical, cosmetic and industrial applications.The number of functional polymers that can be used as parent components for producing novel adhesives is very large, suggesting that the polymer blending approach may revolutionise the adhesive industry in the coming decades.

Pressure-Sensitive Adhesives and Applications, Second Edition explains how pressure-sensitive adhesives (PSAs) work, why they are used, and the technology used to manufacture them. This second edition features the latest developments in the field. Dr. Benedek discusses the factors that affect the rheology and special flow characteristics responsible for the adhesivity of liquid and solid PSAs. His book explores the viscoelastic behavior of PSAs, and compares them to plastics, rubbers, and polymers properties and examines the parameters that influence the conversion process of PSAs from the coating of carrier materials to the properties of the final laminate. The author covers adhesion/cohesion balance, time-temperature dependence of pressure sensitivity, chemical composition, coating properties, and coating processes affect the adhesive properties of PSA and their end products and how application-specific performance indices are used to determine the formulation and manufacture of raw materials. In addition, up-to-date coating machines, converting technology, and environmental considerations in the manufacture of PSA final products as well as industry-specific methods of testing for quality assurance and control are discussed. Pressure-Sensitive Adhesives and Applications, Second Edition combines the theoretical basis of pressure sensitivity with the practical aspects of manufacturing, testing, and use of PSAs. Readers are offered an exhaustive as well as comparative look at the engineering of plastics, adhesives, and pressure-sensitives, resulting in an indispensable, up-to-date reference for adhesive and polymer chemists and technologists.
