Definitions
- the invention relates to a process for the preparation of silicone-modified polymers in the form of their aqueous polymer dispersions or in the form of their polymer powder, and their use, and protective colloids containing silicone units.
- Organosiliciu compounds such as organosiloxane polymers are used for the hydrophobization of polymers of ethylenically unsaturated monomers.
- Such hydrophobically modified polymers are used in many areas in the form of their polymer powder, in particular polymer powder redispersible in water, or as an aqueous polymer dispersion. They are used as binders in coating materials or adhesives, particularly in the construction and textile sectors, and as binders in cosmetics and hair care products.
- EP-A 0352339 describes protective coatings for concrete structures which contain copolymers of divinyl-polydimethylsiloxane with acrylate or methacrylate esters and with vinyl- or acrylic-functional alkoxysilanes as a solution in organic solvents.
- EP-B 771826 describes aqueous binders for coatings and adhesives based on emulsion polymers of vinyl esters, acrylic or methacrylic acid esters or vinyl aromatics which, as crosslinking agents, contain polysiloxanes with unsaturated radicals, for example vinyl, acryloxy or methacryloxy groups
- EP-A 943634 describes aqueous latices for use as coating agents which are obtained by copolymerizing ethylenically unsaturated monomers in the presence of a silicone resin containing silanol groups getting produced.
- EP-A 1095953 describes silicone-grafted vinyl copolymers, a carbosiloxane dendrimer being grafted onto the vinyl polymer.
- silicone-containing polymers can be obtained by polymerizing ethylenically unsaturated monomers in the presence of a linear polydialkylsiloxane with polyalkylene oxide side chains.
- US-A 5216070 describes a process for the inverse emulsion polymerization of carboxyl-functional monomers, linear polydialkylsiloxanes with polyalkylene oxide side chains being used as emulsifiers.
- DE-A 4240108 describes a polymerization process for the preparation of binders containing polysiloxane, for use in dirt-repellent coatings, the monomers being polymerized in the presence of an OH-, COOH- or epoxy-functional polydialkylsiloxane which may also contain polyether groups.
- DE-A 10041163 discloses a manufacturing process for hair cosmetic formulations in which vinyl esters are polymerized in the presence of a polyether-containing compound, for example polyether-containing silicone compounds.
- a disadvantage of the silicone-modified emulsion polymers described in the prior art is a strong tendency to hydrolysis and to uncontrolled crosslinking, which, in some applications, is desired and subsequently increased by adding silane and catalyst, but in the case of paint dispersions or when used as a coating agent undesirable gel bodies, "specks" and insoluble constituents.
- the previously known silicone-containing emulsion polymers are often not alkali-resistant, since it is known that silicones are not stable in alkaline. For this reason, the hydrophobicity and the associated positive effects decrease in the systems described so far Properties decrease very strongly after a long period of time.
- a large amount is introduced insufficient on silanes or silicones
- Particle size distribution that is, the particles become too large and the polymer becomes inhomogeneous, which can result in serum formation or phase separation. Coagulum formation can also occur.
- the object of the invention was to develop polymers which are hydrolysis-resistant and hydrophobic, thereby weather-resistant, water-repellent and not polluting, and moreover have good water vapor permeability and have a high resistance to wet abrasion. Another object was to provide a process by which hydrophobically modified polymers with a narrow particle size distribution and without coagulation are accessible.
