Thanks for your quick response. Further investigation yesterday revealed tiny spiders. I'm wondering if these could be spider mites although research on pc to find picture suggests they are wrong colour and slightly bigger. The areas of cotton wool are in fact tiny spider webs. Also my research into spider mites don't really suggest an attack would kill off an acer, yet alone two, so quickly. Although it must be an infestation of some sort to spread from one acer to another?
Does it look anything like mealy bug? There's some information in the pest section on this site. A former colleague of mine used to use medical alcohol on mealy bug. I used vodka (applied with a small paint brush/ cotton bud) to get rid of it from an acer once before. Cheap vodka is as good as the stuff you might like to drink if so!
I have already lost one acer during the past couple of months, probably foolishly thinking this was due to repotting it. The leaves died back starting at the tip of each branch and then fell off. Eventually the whole tree was affected. The same thing has now started on the Palmatum Bloodgood. I have sprayed with both bug clear and fungus clear during the past month but to no avail. I have noticed on the dead acer which is still in pot but removed to another part of the garden, tiny fluffy loose cotton wool areas all over the tree. Looking carefully at my dying acer, also in a pot, I can see similar strands of cotton wool in one or two places and also on a nearby standard fuschia. I have looked carefully but cannot find any signs of insect. Where the branch has been damaged the wood itself has whitened in places. Help!

This purple foliaged maple will reach 3 m high with a comperable spread. The foliage is a darker colour compared to Acer palmatum 'Atropureum' whose foliage is a dirty red green. The foliage will burn in an exposed location so find a sheltered spot. With such a dark coloured foliage it will lend itself to being planted next to golden bamboos Phyllostachys aurea and variegated foliage plants such as Pittosporum Garnettii and Rhamnus 'Argenteovariegata'.

Great specimen plant whatever style of garden you have. Has to be in the top ten of most loved foliage plants. Deep burgundy colour, good size but not too overwhelming, winter structure, tolerates a wide range of conditions and looks great underplanted with ferns and Brunners' Jack Frost'. Put deciduous Azaleas nearby and wow! Orange is my favorite here and works well with the blue Brunnera flowers.
