A method for cleaning a substrate which is or comprises a textile, the method comprising agitating the substrate in the presence of a cleaning composition comprising: i. cleaning particles comprising a thermoplastic polyamide and a particulate inorganic filler having a density of at least 2.5 g/cm, said cleaning particles having an average particle size of from 1 to 100 mm, wherein the cleaning particles have an average density of at least 1.65 g/cmand/or the particulate inorganic filler has a Dparticle size of at least 10 microns and/or a Dparticle size of at least 40 microns; and ii. a liquid medium.

Cleaning method, apparatus and use

The present invention relates to a process for the production of low-halogen-content polybiphenyl sulfone polymers, to the resultant polybiphenyl sulfone polymers, to polybiphenyl sulfone polymers having less than 400 ppm content of polymer-bonded halogen, to thermoplastic molding compositions comprising these polybiphenyl sulfone polymers, and to their use for the production of moldings, of fibers, of films, of membranes, or of foams.

Method for producing low-halogen polybiphenylsulfone polymers

The present invention relates to a process for the production of low-chlorine-content polybiphenyl sulfone polymers, to the polybiphenyl sulfone polymers obtainable in this way, to polybiphenyl sulfone polymers with less than 800 ppm content of organically bonded chlorine, to thermoplastic molding compositions and moldings, fibers, films, membranes, or foams comprising the polybiphenyl sulfone polymers mentioned, and also to their use for the production of moldings, of fibers, of films, of membranes, or of foams.
