| titleOfInvention | High surface area macroreticular resins crosslinked with a polyfunctional methacrylate |
| abstract | 1275472 High surface area macroreticular resins ROHM & HAAS CO 26 Aug 1969 [30 Aug 1968 30 July 1969] 42501/69 Headings C3C and C3P [Also in Divisions C5 and C6] Cross-linked macroreticular resins having pores with average diameter of at least 15 and a surface area of at least 5 sq. m/g are prepared by polymerizing a monomer charge containing cross-linking monomer which is one or more methacrylates containing at least 3 methacrylate groups, said pores being formed in the polymerized mass by trapping therein a removable material which is a liquid or solventsoluble substance. Polymerization is preferably effected in the presence of a solvent which is miscible with the monomers but which does not dissolve the polymer, and in aqueous suspension to produce polymer beads or granules. The monomer charge preferably contains 2-100% by weight of the polymethacrylate, e.g. trimethylolpropane trimethacrylate, pentaerythritol tetramethacrylate, glycerol trimethacrylate, glucose pentamethacrylate or sorbitol hexamethacrylate. Comonomers which can be used include olefins, acrylic acid, (meth)acrylic nitriles and amides, diacetone acrylamide, vinyl esters, vinyl and vinylidene halides, vinyl ketones, vinyl ethers, (meth)acrylate esters including amino alkyl, hydroxy alkyl and thio alkyl esters, esters of unsaturated di- or tri-carboxylic acids, and di-methacrylates such as those of ethylene glycol and trimethylol propane. The polymer preferably contains at least 75% by weight of aliphatic (including cycloaliphatic) mers. In examples a polymer containing methyl acrylate mers is (a) reacted with hydrazine to form acrylic hydrazide mers, (b) reacted with 3-dimethylaminopropylamine to form amide mers and (c) hydrolysed or acidolysed to introduce ionexchange groups; and a polymer containing 2- ethylthioethyl methacrylate mers is treated with hydrogen peroxide to form mers containing sulphoxide or sulphone groups having good adsorbent properties. |
