Abstract: A process for the prodn. of (1-4C alkyl) (meth)acrylate esters (AM/AE) from esters of formula (I) and opt. esters of formula (II), in which R = H or Me; R , R = 1-4C alkyl; n = 0 or more. The process comprises reaction in the liq. phase under reduced pressure in presence of acid, with continuous removal of cleavage prods. Also claimed is a process for the prodn. of (AM/AE) by the acid-catalysed esterification of 1-4C alkanols with (meth)acrylic acid, in which by-prods. (I) and (II) are sepd. from the prod. mixt. and subjected to the above cleavage process, and the cleavage prods. are continuously removed and returned to the esterification process.

Abstract: A process for the preparation of a compound having the structure of Formula (I) wherein A, R1, R2, R3, Y and Z are as defined in the disclosure. The process includes reacting a heterocyclic amine with a monoaldehyde or a dialdehyde in a pH range of from about 8 to 14 and then quaternizing the so-reacted heterocyclic amine with an alkylating agent at a pH of not less than about 2. The use of a pH control substantially prevents formation of an undesirable protonated intermediate.

Abstract: A process is described for copolymerizing ethylene with vinyl esters and, if desired, with further vinylic comonomers in a tube reactor at pressures of from 500 to 4000 bar and at not more than 220° C., which comprises initiating the free-radical polymerization at at least two locations of the tube reactor by adding a catalyst/initiator and adjusting the temperature profile within the reactor such that the temperature maxima downstream of the initiation locations are from 150 to 220° C. and differ by less than ±10° C. from one another.
