A fluid dispenser device having at least one reservoir (20) that is suitable for containing fluid to be dispensed and a propellant gas; a valve (30), in particular a metering valve, that is mounted on said reservoir (20); and a body (10) including a dispenser orifice (40) via which the fluid is dispensed. The reservoir (20) is movable in the body (10) so as to actuate the valve (30); at least a portion of the dispenser device is made out of a material having an aliphatic polyketone.

A fluid dispenser device having at least one reservoir (20) that is suitable for containing fluid to be dispensed, a dispenser member (1, 30), an actuator member (2, 10) that is suitable for actuating said dispenser member (1, 30); a dispenser orifice (3, 40) via which the fluid is dispensed; and a dose counter or indicator (A). At least a portion of the dose counter or indicator (A) is made out of a material having an aliphatic polyketone.

Carbon-linked 5-hydroxymethylfurfural (HMF) oligomers contain at least one first HMF unit and one second HMF unit. The first and second HMF units are linked by a carbon-carbon bond with involvement of an aromatically bound carbon atom at position 3 or 4 of the furan ring of the first HMF unit. The HMF oligomers may be used as reactive carbonyl compounds in the manufacture of thermally curable resins on the basis of phenolic compounds and/or aminoplastic forming agents as well as in the manufacture of wood composite products.

Self-immolative polymers and compositions comprising such polymers are described. The polymers are copolymers of phthalaldehyde and one or more additional aldehydes and can degrade/decompose upon exposure to a desired stimulus, like light, heat, sound, or chemical trigger. The copolymers can be linear or cyclic, and can be crosslinked or uncrosslinked. Polymer compositions, including multilayered and multiregioned compositions, containing the copolymers are disclosed. These compositions can contain agents such as crosslinking agents, crosslinking catalysts, photocatalysts, thermocatalyst, sensitizers, chemical amplifiers, freezing point depressing agent, photo-response delaying agents, and the like. Methods of making and using the copolymers are also described.
