well that's an interesting question.. let's see..
search google for "lego material plastic carbon"
lots of results.. but this one:
http://www.designinsite.dk/htmsider/m0007.htm
shows us that the material is in fact ABS
- acrylonitrile butadiene styrene
It is an environment-friendly mixture, but this is
not enough.. we need more molecular data :)
Well.. search google for ABS etc.
http://www.polymerprocessing.com/polymers/ABS.html
and.. that's just about it :
Density: 1.02 - 1.21 g/cc 0.0368 - 0.0437 lb/in³
Average = 1.05 g/cc; Grade Count = 185
so... we can see why they just sink in water - since
the legos are a little bit heavier than H2O..
Greetings! and happy building!

| (...) " ABS is an amorphous thermoplastic blend. The recipe is 15-35% acrylnitrile, 5-30% butadiene and 40-60% styrene. Depending on the blend different properties can be achieved." As to the original question, it's hard to talk about the molecular (...) (22 years ago, 6-Mar-03, to lugnet.fun, lugnet.general)
