    Abstract: There are disclosed normally tacky, pressure-sensitive adhesive compositions comprising one or more normally tacky polymers having a Tg of about 0 DEG C. or less and containing pendant functional groups attached to the backbone and having the formula: - R1 - @ - CH2 - X in which R1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano, the polymers preferably also being normally tacky when cured. Such polymers have markedly improved cohesive strength (shear holding value) with little or no detriment to adhesive tack or adhesion (peel resistance), and these improvements are realized without the necessity of incorporating cross-linking monomers such as N-methylolamides or other cross-linking agents. Pressure-sensitive adhesive, water-based emulsions containing such polymers and pressure-sensitive adhesive articles comprising a substrate having at least a portion of one surface thereof coated with the adhesive compositions are also disclosed. In a preferred embodiment, the adhesive compositions further include a polyacid component for further improving cohesive strength, particularly at acidic pH.

    Abstract: A liquid or spreadable, vulcanisable rubber mixture based on a plurality of polymers, of which at least one is olefinically unsaturated, are prepared in such a manner that they can be cured by two different chemical reaction mechanisms which can be activated successively and can be catalysed at least substantially independently of one another. This is achieved by preparing a rubber mixture from - 30-70 parts by weight of a polymer A containing an average of at least 2 hydroxyl groups per macromolecule, - 70-30 parts by weight of a polymer B which is compatible with A and contains an average of at least 2 carboxylic acid and/or carboxylic anhydride groups or at least one carboxylic acid and one carboxylic anhydride group per molecule, - 10-120 parts by weight of vulcanisation assistants and if desired fillers and/or auxiliaries and - if desired 0.01-5 parts by weight of esterification catalysts, at least one of the polymers A and B being vulcanisable via its olefinic double bonds under conventional reaction conditions at elevated temperatures.
