Scientific interest in UV crosslinkable systems developed in the 1940s, when the first patent was granted for unsaturated polyester styrene inks that polymerized readily under UV radiation. Basic solvent-based, water-borne or solvent free pressure-sensitive adhesives (PSAs)—polymers used in self-adhesive tapes, labels and layers—are

In last years Lamberti is betting on a class of photoinitiators called difunctional; three main photoinitiators belong to this class: LFC 1861 (Type I photoinitiator), LFC1001 (Type II photoinitiator) and LFC 2098 (Co-initiator). The several positive characteristics they have, suggested us to improve studies and development of these

Diseases of the cardiovascular system are the main reasons for morbidity and mortality in all western countries. The total direct and indirect costs of cardiovascular diseases (CVD) and stroke for 2007 are estimated at $286 billion for the USA alone.1 Coronary heart disease (CHD) or ischemic heart disease (IHD) plays the most importa

Low energy (less than 300 kV) electron beam (EB) technology has been used for industrial applications for over 30 years. Well known applications include:- Crosslinking of polyethylene based films for packaging applications- Surface sterilization of food and medical packaging- Crosslinking and curing of adhesives- Curing of surface applied inks

The use of UV/EB technology in developing applications such as photovoltaic and flat panel displays demands improved properties in key application parameters such as moisture vapour transmission. Molecular weight, acrylate functionality, solubility parameter and resin backbone have all a direct impact on the efficiency of the ba

Laminated glasses are generally produced with a time, energy consuming and a complicated process by using polyvinyl butyral (PVB). For economic and energetic reasons, a much more efficient process is needed. Therefore in this work a UV curable PVB derivative was used as a binder in glass laminating systems. First PVB was modified with acryloyl chlo

Nanocomposite means a composite into which the filler exhibits one dimension in the “nanonometer” (10−9 m) scale. Composites of polymers and nanofillers have attracted increased attention recent years because of some superior engineering properties compared to neat polymer. Nanosized additives, used as low loadings, can significantly

New alkoxyamines bearing a chromophore group linked to the aminoxyl function are proposed as new photoiniferters. These original compounds decompose under UV irradiation to generate the corresponding alkyl and nitroxide radicals. Laser Flash Photolysis and ESR experiments showed an efficient shortening of the excited state lifetimes
