| titleOfInvention | Sulpho-containing ethyl methacrylate and polymers thereof |
| abstract | The invention comprises <FORM:0989932/C2/1> where X is hydrogen, ammonium, alkali metal or alkaline earth metal. They are prepared by reacting methacrylic acid with 2-hydroxy-1,3-propanedisulphonic acid preferably in the presence of a polymerization inhibitor and at -20 DEG to 100 DEG C. and neutralizing to form a salt if desired. The water formed may be removed azeotropically. The compounds may be polymerized alone or with other monomers (see Division C3) and act as dye assisting adjuvants for the polymers (see Division B5); they can also be used to thicken aqueous emulsions such as natural or synthetic polymer latices (see Division C3).ALSO:The invention comprises polymers, including copolymers, of <FORM:0989932/C3/1> where X is hydrogen, ammonium, alkali metal or alkaline earth metal (for preparation see Division C2). Polymerization may be effected in an aqueous medium, preferably using a free radical type catalyst. In examples, an aqueous mixture containing acrylonitrile, methyl acrylate, the sodium salt of the invention, zinc chloride and Fe+++ and Cu++ ions is polymerized using H2O2. The resulting polymer is spun (see Division B5). Natural or synthetic polymer latices may be thickened by means of the polymers of the invention. In an example, a styrene-butadiene latex is thickened with the polymer of the disodium salt.ALSO:2-Sulpho-1-sulphomethylethyl methacrylate and its ammonium, alkali metal and alkaline earth metal salts are used as copolymerisable monomers to give polymer fibres of improved receptivity to basic dyes. In examples sodium 2-sulpho-1-sulpho-methylethyl methacrylate is copolymerised with acrylonitrile and methyl acrylate and fabrics prepared from the resulting polymer are dyed with Calcozine Acrylic Violet 3R Basic. |
