Abstract: 1,142,330. Olefinically unsaturated compounds containing urethane- or urea-methylol alkyl or alkenyl ether groups. FARBENFABRIKEN BAYER A.G. 30 Dec., 1965 [30 Dec., 1964], No. 55242/65. Heading C2C. [Also in Divisions B2 and C3] Olefinically unsaturated compounds have the general formula in which Y denotes an alkylene group containing more than one carbon atom, or an aralkylene or cycloalkylene radical which may contain, as bridge members and/or substituents, carboxylic acid amide, carboxylic acid ester, ether, tertiary amino, urea, urethane or sulphonamide groups, halogen atoms, or cyclic radicals containing oxygen, sulphur or nitrogen atoms, n is an integer of from 1 to 3 and (i) A denotes a vinyl or vinylidene radical which is linked to radical Y directly and X is O or S, in which case R is an alkyl or alkenyl radical or X is NR 1 , in which R 1 is a hydrogen atom or an alkyl or alkenyl group, in which case R is an alkyl or alkenyl radical, or (ii) A denotes a vinyl or vinylidene radical which is linked to Y through a carboxylic acid ester or amide group, and X is O or S, in which case R is an alkyl or alkenyl radical, or X is NR 1 in which R 1 is a hydrogen atom or an alkyl or alkenyl group, in which case R is an alkenyl radical, or (iii) A denotes a vinyl or vinylidene radical which is linked to Y through an ether group, and X is O or S, in which case R is an alkenyl radical or X is NR 1 , in which R 1 is a hydrogen atom or an alkyl or alkenyl radical, in which case R is an alkyl or alkenyl radical, which alkyl and alkenyl radicals R and R 1 contain 1 to 18 carbon atoms and may be branched. The compounds are prepared by (i) reacting a compound containing an olefinic bond and phenolic or alcoholic hydroxy groups or primary or secondary amino groups with an alkoxy or alkenoxy methylisocyanate or (ii) reacting an amino or hydroxy compound with an alkoxy or alkenoxy methylisocyanate to form a compound containing at least one phenolic or alcoholic hydroxyl group or a primary or secondary amino group and introducing a polymerizable radical into said compound, e.g. by acylation or alkylation. Descriptions are given of the preparation of propanediol-2-N-methoxymethylurethane-1-methacrylic acid ester in Example 1, the compound in Example 5, the compound in Example 6, the compound in Example 7 and the compound in Example 8.

Abstract: A process for the polymerization of aromatic vinyl compounds and their copolymerization with alkyl esters or nitriles of acrylic and/or methacrylic acid, wherein 1. IN A FIRST STAGE, THE MONOMER OR MONOMERS IS OR ARE CONTINUOUSLY INTRODUCED AT EXCESS PRESSURE INTO A FIRST REACTION ZONE AND POLYMERIZED THERE TO A DEGREE OF CONVERSION OF 5 - 40% BY WEIGHT AT A TEMPERATURE OF FROM 80 DEG TO 170 DEG C; 2. in a second stage, the reaction mixture is conducted at constant pressure into a second reaction zone designed for conducting highly viscous melts, the mixture flowing through this reaction zone at a rate which is 1.1 to 5 times the intrinsic rate, and polymerized there to a degree of conversion of 40 to 95% at temperatures of from 120 DEG to 250 DEG C, the excess pressure in the first and second stage being chosen so that the monomer or monomers is or are liquid, and the polymer is continuously removed from this zone with release of the pressure; and 3. IN A THIRD STAGE, UNREACTED MONOMER IS REMOVED BY EVAPORATION, THE PRESSURE BEING CHOSEN SO THAT THE MONOMER OR MONOMERS IS OR ARE EVAPORATED, AND THE POLYMER IS DISCHARGED AS A MELT.
