Abstract: A single-layer or multilayer film formed from one or more polymeric materials has CIE colour values a* and b* such that −7≤a*≤0, −15≤b*≤0 and an optical transmission T such that 60%≤T≤95%. The inventive transparent films provide discoloration compensation that alleviates yellowing caused by UV light.

Abstract: Solid additive particles are added to solid vinylidene chloride (VDC) polymer particles by a process comprising the steps of: A. Polymerizing VDC monomer, optionally with one or more mono-ethylenically unsaturated comonomers, in a polymerization zone under polymerization conditions to form solid VDC polymer particles; B. Stopping the polymerization of the VDC monomers after formation of the solid VDC polymer particles; and C. Contacting the solid VDC polymer particles with the solid additive particles (i) before the solid VDC polymer particles are de-watered, and (ii) at a temperature sufficient to melt or soften the solid additives particles but insufficient to melt or soften the solid VDC polymer particles such that the melted or softened solid additive particles adhere to the solid VDC polymer particles upon contact.

Abstract: A vinyl chloride-based copolymer porous body contains a vinyl chloride-based copolymer as the main component. The vinyl chloride-based copolymer porous body has continuous pores having a pore size of 0.1 to 40 μm, the pores have a skeletal diameter of 0.1 to 20 μm, and the vinyl chloride-based copolymer has a thickness of 1 mm or more. Such a vinyl chloride-based copolymer porous body can be produced by a production method including the steps of: heating and dissolving the vinyl chloride-based copolymer in a solvent to obtain a vinyl chloride-based copolymer solution; cooling the vinyl chloride-based copolymer solution to obtain a precipitated product; and separating and drying the product to obtain a porous body containing the vinyl chloride-based copolymer as the main component.
