Abstract: A container body comprises a base, a side wall extending from the base and a neck portion arranged to engage a closure for the container body, wherein: (i) said container body includes a cyclic olefin copolymer (COC) and polyester; or (ii) said container body includes a polymethylpentene (PMP) and polyester; wherein, in both cases (i) and (ii), the side wall of the container body has an L* of at least 90 and the neck portion has an L* of at least 84.

Abstract: Abstract: A container body which comprises a base and a side wall extending from the base, wherein said container body includes a polyester and a polymer YY. wherein said polymer YY is selected from the group comprising cyclic block copolymers (CBC) and cyclic olefin polymers (COP).

Abstract: A preform for a container comprises a polymer composition which includes tungsten oxide particles, for example WO2.72 or WO2.92.

Abstract: A preform is made by mixing cyclic olefin copolymer (COC) and light shielding pigment(s) with PET. The preform is stretch-blow moulded to produce a bottle which may be white and opaque. Light may be restricted from entering the bottle to thereby restrict degradation of the bottle contents from certain wavelengths of visible light.

Abstract: The application provides a method of producing a comb polymer comprising the steps of: (a) Providing: (i) a plurality of monomers which are linear, branched or star-shaped, substituted or non-substituted, and have an olefinically unsaturated moiety, the olefinically unsaturated moiety being capable of undergoing addition polymerisation; (ii) an initiator compound; the initiator compound comprising a homolytically cleavable bond. (iii) a catalyst capable of catalysing the polymerisation of the monomer; and (b) Causing the catalyst to catalyse, in combination with the initiator, the polymerisation of a plurality of the monomers to produce the comb polymer. Catalysts and polymers obtainable by the process are also provided. Preferably, the comb polymer is capable of binding proteins and may be produced from monomers which are alkoxy polyethers, such as poly(alkyleneglycol) or polytetrahydrofuran.
