    摘要： A method is disclosed for inhibiting the polymerization of acrylic and methacrylic acids at ambient or above ambient temperature, such as during preparation, purification or storage of the acids under substantially anaerobic conditions, by adding thereto a polymerization inhibiting amount of a compound having the formula:R--NOwhere R is alkyl or aryl, and if R is aryl, a hydroxyl group para to the NO group enhances inhibition.

    摘要： Disclosed are homopolymers and copolymers of a monomer or a mixture of monomers having the formula ##STR1## in which the average value of n (n) is in the range from greater than 1 to about 10, being oligomeric usually prepared from acrylic acid. In the mixtures of such monomers, the number n may range from 1 to 30 or more. Also disclosed are methods of preparing the polymers, methods of using them, and articles of manufacture containing the polymers.

    摘要： An improved continous single step vapor phase process for the preparation of substituted vinylbenzyl chloride from substituted ethyltoluene is disclosed. In this process a substituted ethyltoluene is reacted with a halogen gas in the vapor phase, at elevated temperatures via a continuous feed process. Furthermore, this process achieves halogenation followed by dehydrohalogenation in a single pass through the reactor. There is also obtained a very high total selectivity to vinylbenzyl chloride and its precursors via this continuous process.

    摘要： The quaternary ammonium monomers of this invention have the formula ##STR1## wherein R is an ethylenically unsaturated organic groupR.sup.1 is a linear C.sub.1 to C.sub.4 alkyl group, optionally hydroxy substitutedX is chlorine, bromine or iodineY.crclbar. is a surfactant anion.The epoxides derivable from the halohydrin of Formula (I) are other monomers of this invention.The monomers are soluble in common organic solvents and comonomers. The invention is also directed to addition polymers of these monomers and to methods of producing both the monomers and the polymers. The halohydrin monomers and the polymers are stable at acid pH values, although capable of reacting with materials reactive with the hydroxyl and/or halide groups. Upon heating, they are self-reactive and can become cross-linked. At alkaline pH values they become self-reactive; the polymers crosslink slowly even at room temperature, with a crosslinking rate increasing rapidly with temperature. The monomers are particularly efficiently incorporated into copolymers.
