    摘要: The invention relates to a process for the production of (meth)acrylic acid esters of polyhydric alcohols by reaction of the reactants with acrylic acid and/or methacrylic acid in the presence of acidic esterification catalysts with addition of sterically hindered phenolic compounds as polymerization inhibitors. The process is characterized in that tocopherols are used as the sterically hindered phenolic compounds and .alpha.-tocopherol is preferably at least partly used. The process is preferably carried out using reaction mixtures which are liquid at room temperature and which are at least substantially free from solvents and/or azeotropic entraining agents; more particularly, the water of condensation formed is removed from the gas phase of the reaction zone.

    摘要: The invention relates to a process for the production of (meth)acrylic acid esters of polyhydric alcohols by reaction of the reactants in the presence of acidic esterification catalysts with addition of .alpha.-substituted phenolic compounds, more particularly di-tert.-butyl hydroquinone, as polymerization inhibitors. The new process is characterized in that the reaction mixtures used are liquid at room temperature and are at least substantially free from solvents and/or azeotropic entraining agents and in that the water of condensation formed is removed from the gas phase of the reaction zone.

    摘要: (Meth)-acrylate compounds having one or two terminal (meth)-acrylic acid groups on an oligomer chain which have low volatility and are liquid to solid at room temperature, wherein the oligomer chain is mainly in the form of a polyester oligomer formed from one or more hydroxycarboxylic acids. The preferred (meth)-acrylate compounds are based on polyester-oligomers with a mean molecular weight in the range of about 200 to 600. The invention also relates to the use of these new reactive (meth)-acrylate compounds in construction adhesives.

    摘要: A guitar case comprising a resiliently flexible first teardrop oval shell defining a guitar receptacle for operatively receiving a guitar, the first shell including a guitar suspension arrangement comprising a body strap configured to operatively secure a body of the guitar away from a side of the receptacle, and a neck strap configured to operatively secure a neck of the guitar within the receptacle. Case 10 also includes a resiliently flexible second teardrop oval shell configured to operatively complementarily engage the first shell in a clamshell manner, and fastening means configured to fasten the shells together such that at least the upper shell elastically deforms over the guitar receptacle to sandwich the guitar suspended within the receptacle between the shells.
