Abstract: A method of making an acrylate monomer from an essentially ethoxylated polyol, which monomer has a reduced and very low Primary Irritation Index (PII value). The base polyol is di, tri, tetra or polyhydroxyfunctional and the reduced PII value is obtained by reducing the formation of by-products such as monoethylene, diethylene and triethylene glycol during the ethoxylation of the base polyol. A polyol is reacted with propylene oxide at a molar ratio of 1:0.5-1:2.5 and in the presence of an alkali metal hydroxide catalyst. The polyol propoxylate obtained is reacted with ethylene oxide at a molar ratio of 1:2-1:10, whereby an ethoxylated polyol propoxylate with an average molecular weight of 270-500 is obtained. The ethoxylated polyol propoxylate is finally acrylated to yield an acrylate monomer having at least one acrylic unsaturation.

Abstract: Storage container, preferably a storage tray (1) of plastic having detachable partition walls (2), the container being provided with opposite vertical recesses or pairs of vertical ledges (5) along the inner side of the two long sides (3, 4). The container (1) comprises an inwards directed horizontal ledge (6) at the top along the inner side of each of the two long sides (3, 4), locking means (7) arranged in the upper edge of the ledges (6) on the two long sides (3, 4) of the container (1) in connection with each recess or pair of ledges (5), partition walls (2) including a lower part (8) and an upper part (9) connected to each other by an integrated hinge (10), whereby the parts (8, 9 and 10) are made of plastic in one piece, the upper part (9) being provided with locking means (11) along each short side which locking means (1 1) arc intended to co-operate with the locking means (7) on the container (1).
Abstract: The invention relates to a dendritic macromolecule of the polyester type comprising a central initiator molecule or initiator polymer having one or more reactive hydroxyl groups (A). The groups (A) are under formation of an initial tree structure bonded to reactive carboxyl groups (B) of a monomeric chain extender having the two reactive groups (A) and (B). The tree structure is optionally extended and further branched from the initiator molecule or initiator polymer by addition of further molecules of a monomeric chain extender by means of bonding between the reactive groups (A) and (B) thereof and is thereafter optionally further extended by reaction with a chain stopper. The invention also comprises a process for preparation of the dendritic macromolecule.
