Patent GB-830812-A (GB)
Title: Improvements in or relating to alkyd resins
IPC: C08G63/127
Filed: 1957-11-20
Abstract: An alkyd resin is obtained by polyesterifying a polyhydric alcohol with one or more dimethylbenzene dicarboxylic acids obtained by chloromethylating one or more xylenes and subsequently oxidizing the resulting chloromethyl derivatives.  The preparation of the acids is claimed in Specification 771,086, [Group IV (b)].  Lacquers are obtained by effecting the polyesterification in the presence of an unsaturated fatty acid or oil and also, if desired, of pyromellitic acid.  Mouldings are obtained by effecting polyesterification in the presence of an unsaturated polycarboxylic acid (e.g. fumaric, maleic, citraconic or itaconic acid) and polymerizing the resulting unsaturated alkyd with a solvent containing a vinyl group.  In the examples oxidized chloromethyl derivatives of crude xylene are used consisting chiefly of a mixture of 1,3-dimethyl - 4,6 - benzene - dicarboxylic acid, 1,4 - dimethyl - 2,5 - benzene - dicarboxylic acid and 1,2-dimethyl-4,5-benzene-dicarboxylic acid.  In the examples: (1)-(3) an alkyd from dimethyl benzene dicarboxylic acids, glycerol and linseed oil or linseed fatty acids was dissolved in benzene, toluene or xylene containing cobalt and lead naphthenate to produce a lacquer; (4) an unsaturated alkyd from dimethylbenzene dicarboxylic acid, maleic anhydride and diethylene glycol was copolymerized with styrene in the presence of benzoylperoxide and cobalt naphthenate; (5) and (6) an alkyd from dimethylbenzene dicarboxylic acids, pyromellitic acid, glycerol and linseed oil or soya bean oil was dissolved in toluene or xylene containing lead and cobalt naphthenate to produce a lacquer.

The baffle 2 is adjustably mounted on a bracket 4 which is carried by a truck 7 running in tracks 9, and thus can adjust to different strip widths. The roller 10 keeps the baffle 2 at the required distance from the strip edge. The lower portion 2b of the baffle 2 is curved so that in operation a pressure differential arises between the strip side of the baffle and the back, the resulting thrust urging the baffle towards the strip. In modifications, the baffles can be carried at the ends of swingable arms, or on one arm of parallelogram linkages. The tracks 9 may be tilted so that the truck 7 runs towards the edge of the strip 1. Steam can be used instead of air; the coating liquid may be paint, glue, or molten metal, and the strip may be paper.
