    摘要: There is provided a curable anaerobic pressure sensitive adhesive composition, a mixture of a curable anaerobic system and a high molecular weight polymer system. The mixture which may include a tackifier and other functional additives constitutes a pressure sensitive adhesive and exhibits elastomeric properties. There is also provided in the composition an initiator systemnecessary to permit curing of the anaerobic pressure sensitive composition upon activation by the exclusion of oxygen. One or more accelerators for cure may also be provided.In one embodiment a component of the catalyst system may be either absent and provided later or latently present in microspheres which upon rupture will enhance the curing operation.

    摘要: A process for the polymerization of vinyl or vinylidene-group-containing esters in the presence of a free radical generating compound as an initiator and a metal compound as an accelerator comprising, as an initiator, an organic peroxidic composition consisting essentially of a compound having the general formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be the same or different and each represents hydrogen, branched or unbranched alkyl, if desired substituted by hydroxy, alkoxy, alkoxycarbonyl or halogen, aryl, if desired substituted by alkyl, hydroxy, alkoxy or halogen, or aralkyl wherein the aryl group may be substituted by alkyl, hydroxy, alkoxy or halogen, and wherein R.sub.1 together with R.sub.2, R.sub.3 together with R.sub.4, and R.sub.1 together with R.sub.4 form a branched or unbranched alkylene group, and R.sub.1 together with R.sub.2 and R.sub.3 form a branched or unbranched alkylylidene group.

    摘要: New copolymers obtained by interpolymerization of alkylacrylate (25 to 85 %), methacrylic acid (15 to 75 %), trialkyloxyvinylsilane (0.1 to 2 %) and monomer acting as reticulating agent, for example: divinylbenzene, alkyl compound, etc. (0.01 to 0.5 %). The above indicated percentages are in weight of the total monomer mixture.These copolymers are used, in form of emulsions, as thickening agents for aqueous systems of polymers, for example of acrylic copolymers.
