Transient 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. Films comprising the copolymers and devices comprising surfaces coated with the film are also described.

The present invention discloses a ketone-aldehyde modified resin and the preparation process thereof. The ketone-aldehyde modified resin comprises a ketone-aldehyde modified unsaturated polyester, a ketone-aldehyde modified unsaturated alkyd or the combination thereof, and wherein the said resin has ketone-aldehyde moieties. The process of the said resin comprises the steps of: reacting unsaturated polyester-forming and/or unsaturated alkyd resin-forming monomer components with a ketone-aldehyde resin. The present invention also discloses a coating composition comprising the said resin as well as a coated article. The ketone-aldehyde modified resin and the coating composition achieve significantly improved fast drying effect, while other properties are not observably impaired or even improved.

A fluid dispenser device having at least one reservoir (20) that is suitable for containing fluid to be dispensed; a pump (1) that is mounted on the reservoir (20); and a dispenser head (2) including a dispenser orifice (3) via which the fluid is dispensed, which dispenser head is suitable for actuating said pump (1). At least a rigid and/or non-deformable portion of the dispenser device is made out of a material comprising an aliphatic polyketone.

The disclosed relates to a polyalkylene carbonate resin composition, and more specifically, to a polyalkylene carbonate resin composition containing polyalkylene carbonate and polyketone. The polyalkylene carbonate resin composition particularly exhibits excellent thermal stability, while having excellent transparency and flexibility, oxygen barrier properties, and mechanical and chemical properties.
