    Abstract: A continuous process for the production of pressure sensitive adhesive mass compositions and adhesive elements which exhibit excellent properties with respect to a variety of substrates, which is non-toxic and non-sensitizing. The element exhibits high cohesive strength so that its integrity is maintained on removal from the substrate leaving no residues and is highly flexible so that total confirmation with the underlying shape of the substrate is maintained. The adhesive composition includes the hydrolysis/esterification product of a methyl vinyl ether/maleic anhydride copolymer with an hydroxylated compound. In this invention, the adhesive element is prepared by microwave heating of a mixture of the copolymer and hydroxylated compound, preferably with a surfactant, in the presence of water.

    Abstract: What is described herein is a process for making ethanol solutions of alkyl half-esters of copolymers of maleic anhydride and a C1-C4 alkyl vinyl ether which are benzene and acetone-free. The invention is characterized by (a) precharging a reactor with excess C1-C4 alkyl vinyl ether as both monomer reactant and solvent, and a free radical polymerization intiator, at a reaction temperature; (b) feeding the alkyl half-ester of maleic anhydride formed by reaction of substantially one mole of maleic anhydride and substantially one mole of alkanol into the precharged reactor to form the desired alkyl half-ester of the alternating copolymer of maleic anhydride and the C1-C4 alkyl vinyl ether in excess alkyl vinyl ether as solvent; (c) cooling the reactor to room temperature; and (d) introducing ethanol solvent into the reactor and removing excess alkyl vinyl ether to form the desired half-ester copolymer in ethanol solution.
