Abstract: A method of preparing a foamed thermoplastic polymer comprises contacting a chemical blowing agent (A) which is a semi-carbazide with a thermoplastic polymer or a precursor of a thermoplastic polymer. Blowing agent (A) is preferably p-toluenesulfonyl semi-carbazide and said polymer is preferably PVC. Formulations, including liquid formulations which include the blowing agent (A) and other ingredients, are also described.

Abstract: A method of producing a product, for example a stretch blow moulded container having a metallic or pearlescent appearance, comprises selecting a mass, for example a container preform, comprising a thermoplastic polymer which incorporates a carrier polymer and stretching the thermoplastic polymer during production of said product, for example from said mass. Said carrier polymer is suitably polydimethylsiloxane and the mass may be made in a process which comprises contacting a thermoplastic polymer with a liquid formulation comprising carrier polymer and colourant.
