The invention describes a novel process for the preparation of polycarbonate and/or polyarylate block copolymers with poly(aryl ethers). The process is comprised of the steps:

Process for the preparation of polycarbonate and/or polyarylate block

Described are crystalline block copolymers displaying high glass transition temperatures, excellent mechanical properties, excellent chemical and thermal stability, and good melt processability. These block polymers contain segments of crystalline poly(aryl ether ketones).

Bis(acid chloride) terminated polyaryl ether ketone oligomer

Photopolymerizable compositions, based on 2-methoxytetrahydropyran and 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carboxylate, which can be applied as coatings on substrates and photocured at high speeds.

Photo curable blends of 2-methyoxytetrahydropyran and a cycloaliphatic

This invention is directed to photocopolymerizable compositions comprising an epoxide containing two or more epoxy groups, a poly (active hydrogen) organic compound, a photoinitiator and, as a reactive diluent, a substituted cycloaliphatic monoepoxide. The photocopolymerizable compositions have low viscosity and can be applied to suitable substrates by conventional methods and, after being cured to dry coating films, can have utility as automotive finishes, can finishes, appliance finishes, general metal finishes, adhesives, printing inks and the like.

Photocopolymerizable compositions based on epoxy and hydroxyl-containing

Described herein are novel poly(aryl ether) polymers that contain naphthalene, terephenylene and/or anthracenylene units within their chains. Representative polymers are tough materials having excellent high temperature, oxidative and chemical resistance, and easy melt fabricability.

Poly (aryl ether ketone) block copolymers

Described herein are novel poly(aryl ethers) based on 2,5-di-t-butylhydroquinone. These poly(aryl ethers) have excellent high temperature, oxidative and chemical resistance, as well as good melt-fabricability.

Novel poly(aryl ethers)

Described herein are compositions suitable for photocopolymerization comprising a cyclic vinyl ether containing compound and an epoxide. These compositions can be cured to give coatings with improved flexibility and impact resistant properties.

Blends, of cyclic vinyl ether containing compounds and epoxides

This invention is directed to photocopolymerizable compositions comprising a poly (active hydrogen) organic compound, a photoinitiator and, as a reactive diluent, a substituted cycloaliphatic monoepoxide. The photocopolymerizable compositions have low viscosity and can be applied to suitable substrates by conventional methods and, after curing, provide excellent pressure sensitive and heat-activated adhesive coatings.

Photocopolymerizable compositions based on hydroxyl-containing organic

Lactone acrylates and organic anhydrides are condensed to form carboxyl-terminated lactone acrylates. These can be homopolymerized or copolymerized with ethylenically unsaturated monomers by means of radiation.
