Abstract: The invention relates to acrylate polymers comprising a K-value ranging from 10 to 60, which can be obtained by the radical polymerization of: 30 to 99 wt. % of tert-butyl acrylate and/or tert-butyl methacrylate designated as monomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomer B, and; 0 to 60 wt. % of a radically copolymerizable monomer or of a radically copolymerizable monomer mixture designated as monomer C, whereby at least one of monomers C yields a homopolymer with a glass-transition temperature lower than 30° C., with the provision that the wt. %'s total 100. The radical polymerization is carried out in the presence of alkane thiols with a C chain length of C 14 to C 22. The invention also relates to acrylate polymers comprising a K-value ranging from 10 to 60, which can be obtained by the radical polymerization of: 30 to 99 wt. % of tert-butyl acrylate and/or tert-butyl methacrylate designated as monomer A; 1 to 28 wt.

Abstract: A process for reducing the amount of residual monomer in aqueous polymer dispersions operates by aftertreatment with an initiator system essentially comprising a) from 0.001 to 5% by weight, based on the total monomer amount used to prepare the polymer dispersion, a1) of an oxidizing agent R1OOH,  where R1 is hydrogen or a C1-C8-alkyl or a C6-C12-aryl group, and/or a2) of a compound which in aqueous medium releases hydrogen peroxide, and b) from 0.005 to 5% by weight, based on the total monomer amount used to prepare the polymer dispersion, of a reducing agent prepared from b1) an aldehyde R2CH═O,  where R2 is a C1-C12-alkyl group which may contain functional groups and/or may be olefinically unsaturated, and b2) an inorganic dithionite, and c) catalytic amounts of a polyvalent metal ion which is able to exist in a plurality of valence states.

Abstract: A bed bridge (10) for converting a pair of beds (12) and (14) into a larger sized bed comprising a platform member (16) and an elongated protrusion (18) projecting downwardly from the center of the platform member (16). When the platform member (16) is placed upon juxtaposed portions of the top surfaces (20) and (22) of two adjacent mattresses (24) and (26) of the beds (12) and (14), the elongated protrusion (18) will extend down between the sides (28) and (30) of the two adjacent mattresses (24) and (26). When the two adjacent mattresses (24) and (26) are pushed together, the elongated protrusion (18) will then cause the platform member (16) to properly position itself on the juxtaposed portions of the top surfaces (20) and (22) of the two adjacent mattresses (24) and (26).
