APPLICATION OF AMPHIPHILIC COPOLYMERS AS AGENTS, IMPROVING THERMAL STABILITY AND RESISTANCE TO UV RADIATION OF CHLORINATED THERMOPLASTIC MATERIALS, CONTAINING FILLING AGENT, METHOD OF OBTAINING THEREOF Russian patent published in 2014 - IPC C08L27/04 C08L33/00 C08K3/26 

FIELD: chemistry.

SUBSTANCE: invention consists in the application in a filled chlorinated thermoplastic composition, containing chlorinated thermoplastic resin and a mineral filling agent as an agent improving thermal stability and resistance to UV radiation of the said composition, of a linear amphiphilic copolymer, consisting of a hydrophilic monomer and a hydrophobic monomer and having the weight average molecular weight from 5000 g/mol to 20000 g/mol, the polydispersity coefficient lower or equal 3, preferably with its weight average molecular weight constituting from 10000 g/mol to 15000 g/mol and the polydispersity coefficient lower or equal 2.5. The invention also relates to a method of obtaining the filled chlorinated thermoplastic composition with the application of the said copolymer, as well as to a composition, obtained directly by the claimed method.

EFFECT: increased thermal stability and resistance to UV radiation of the filled material.
