A binder for textile structures which are graft copolymer latices in which the following are incroporated in the graft copolymer:

Polysiloxane graft copolymer latex for strengthening textile structures

The invention relates to thermoplastic PVC molding compounds containing specially synthesized silicone graft rubbers. These thermoplastic molding compounds show an excellent combination of properties such as impact strength at room temperature, impact strength at low temperatures and particularly high resistance to ageing under the effect of light, moisture and heat.

PVC-silicone rubber molding compounds showing toughness at low

The invention relates to thermoplastic polycarbonate molding compositions containing polycarbonates, special siloxane-containing graft polymers and, optionally, lower thermoplasts and/or standard additives and to a process for the production of the polycarbonate molding compositions.

Mixtures of polycarbonates with siloxane-containing graft polymers

Thermoplastic molding compounds of polyphenylene ether, a graft polymer of resin-forming monomers on silicone rubber and, optionally, a resin-like thermoplastic, a process for their production and their use for the production of moldings.

Polyphenylene ether molding compositions

The invention relates to thermoplastic polycarbonate molding compositions containing polycarbonates, special siloxane-containing graft polymers and, optionally, other thermoplasts and/or standard additives and to a process for the production of the polycarbonate molding compositions.

The invention relates to thermoplastic particulate graft polymers of a rubber (AB), consisting of a core (A) of rubber-like polymer of olefinically unsaturated monomers having softening temperatures (glass temperatures) below 0.degree. C. and a shell (B) of organopolysiloxane, and a polymer (C) of at least one ethylenically unsaturated monomer grafted into the rubber (AB) and to their use, optionally in admixture with brittle thermoplastic vinyl resins, as thermoplastic molding compositions.

Thermoplastic silicon rubber graft polymers (II)

Thermoplastic particulate graft polymers comprising particles of a core (A) of an organic resin-like polymer of olefinically unsaturated monomers having softening temperatures (glass temperatures) above 30.degree. C., a shell polymer (B) or ogranopolysiloxane and a polymer (C) of at least one .alpha.,.beta.-unsaturated olefinic monomer grafted onto the particles consisting of A and B and their use as thermoplastic molding compositions.

Thermoplastic silicone rubber graft polymers (I)

Particulate, multiphase polymers which have a core (A) and an overlying shell (B) wherein the core (A) is an organic, resinous polymer comprising polymerized olefinically unsaturated monomer units having softening point temperatures of at least 30.degree. C. and wherein the shell (B) is an organopolysiloxane are obtained by producing in a first stage an organic resinous polymer in latex form by emulsion polymerization and, in a second stage, the latex particles of the first stage are surrounded with a shell (B) organopolysiloxane by polymerizing low molecular weight organosiloxanes in the presence of the latex particles of the first stage.

Particulate multiphase polymers

Particulate, multiphase polymers which have a core (A) and an overlying shell (B) wherein the core (A) is an organic, rubber-like polymer comprising polymerized olefinically unsaturated monomer units having softening point temperatures below 0.degree. C. and wherein the shell (B) is an organopolysiloxane are obtained by producing in a first stage an organic rubber-like polymer in latex form by emulsion polymerization and, in a second stage, the latex particles of the first stage are surrounded with a shell (B) or organopolysiloxane by polymerizing low molecular weight organosiloxanes in the presence of the latex particles of the first stage.
