An agent is provided which renders compatible at least two incompatible thermoplastic polymers. The agent contains one di- or trisequenced copolymer comprising at least one N-vinyl pyrrolidone or methyl (meth) acrylate telomer and one mono- or difunctional oligomer selected from the group consisting of an ethylenically unsaturated polymerizable monomer, or a polycondensable monomer, or a lactam. The agent is prepared by condensation of the telomer with the oligomer and is used in the preparation of alloys of incompatible thermoplastic polymers.

Agent for rendering compatible at least two incompatible thermoplastic

An agent is provided which renders compatible at least two incompatible thermoplastic polymers. The agent contains one di- or trisequenced copolymer comprising at least one N-vinyl-pyrrolidone or methyl (meth) acrylate telomer and one mono- or difunctional oligomer selected from the group consisting of an ethylenically unsaturated polymerizable monomer, or a polycondensable monomer, or a lactam. The agent is prepared by condensation of the telomer with the oligomer and is used in the preparation of alloys of incompatible thermoplastic polymers.

The invention relates to amine salts of phosphorous acid having a structure of the s-triazine, 1,2,4-triazole, benzimidazole, heptazine, pyrimidine, or piperazine type which may be combined with a polyhydroxylated compound as fireproofing agents for plastics, particularly polyamides and polyolefins, the process of fireproofing said plastics, and the resultant fireproofed plastics.
