Abstract:
Disclosed are photo or electron beam curable polymerizable compositions, and preparation thereof and devices (101)containing such cured material. The composition contains completely or substantially completely hydrogenated hydrocarbon-based material completely free or substantially free of carbon-carbon double and triple bonds containing photo or electron beam curable terminal or pendant groups, low-outgassing photoinitiators, an optional viscosity adjustment component and an optional filler. The composition is visible light, UV or electron beam curable. It cures into a low-modulus, low outgassing polymer material. The composition can be used as an adhesive, sealant or lens potting material (103,107). It is ideal for use in lithographic tools and other optical devices involving deep or vacuum ultraviolet radiations, in particular, as lens potting materials (107,103) for 248 nm, 193 nm and 157 nm lithographic tools, as well as other optical devices involving using high fluence irradiation.
Abstract:
An aqueous adhesive composition for treating a reinforcing fiber for bonding to a thermosetting polymer matrix and products made therefrom such as power transmission belts. The adhesive composition includes: water as the solvent or dispersing medium; a polyelectrolyte co-curable with the polymer matrix; a primer material compatible with the fiber and co-curable with the polyelectrolyte; and optionally a rubber curative compatible with the polyelectrolyte and the polymer matrix. A fiber-reinforced, composite polymer system may thus include a thermosetting polymer matrix, a reinforcing fiber embedded therein, and an adhesive composition coating the fiber; the adhesive composition including a polyelectrolyte co-curable with the polymer matrix and a primer material compatible with the fiber and co-curable with the polyelectrolyte. The adhesive composition may include a curative compatible with the polyelectrolyte. In one preferred embodiment, the invention is an aqueous adhesive composition including water, an epoxy resin, a maleated polybutadiene derivative, and a curative.
Abstract:
Die vorliegende Erfindung betrifft Verbindungen, welche Aminogruppen-terminierte Zähigkeitsverbesserer sind, deren Folgeprodukte sowie deren Verwendungen. Die erfindungsgemässen Zähigkeitsverbesserer weisen die Formel (I) auf. Hierbei steht R 1 für einen divalenten Rest eines Carboxylgruppen- terminierten Butadien/Acrylonitril-Copolymers nach Entfernung der terminalen Carboxylgruppen. Die Verbindungen erhöhen die Zähigkeit der damit formilierten Zusammensetzungen. Insbesondere von Bedeutung sind Glycidylgruppen enthaltende Verbindungen als deren Folgeprodukte, welche in hitzehärtenden einkomponentigen Epoxidharzklebstoffen verwendet werden können.
Abstract:
A synthetic chloroprene rubber adhesive composition which comprises a carboxylated synthetic chloroprene rubber as a major component and further contains a chlorinated polypropylene and/or a chlorinated polypropylene derivative. The composition can tenaciously bond the polypropylene resin used as speaker frames, etc. to adherends, unlike conventional synthetic chloroprene rubber adhesives which have only a poor bonding strength in this application.
Abstract:
The invention concerns two-component compositions which can be cross-linked at room temperature and pressure and which are based on liquid polymers containing acid-anhydride groups and on sterically hindered aromatic di- or polyamines. These compositions are characterized by their low toxicity and controllable cross-linking behaviour. The cross-linked products have high mechanical strength, high thermal stability and high stability to hydrolysis. The invention also concerns methods of preparing such compositions and their use as coating compounds, casting compounds, sealing compounds and adhesives.
