## Abstract A silicon‐containing hyperbranched polymer (__hb__‐P**1**/**2**) with __σ__\*–__π__\* conjugation was prepared in a good yield and high molecular weight by rhodium‐catalyzed alkyne polyhydrosilylation of 1,2‐bis(4‐ethynylphenyl)‐1,2‐diphenylethene (**1**) with tris(4‐dimethylsilylphenyl

Coals and macerals show a measurable extent of expansion in CO, at ambient temperature which is a function ofC0, pressure. Equilibrium expansion is much more rapidly attained in CO, than in methanol. At similar relative pressures, expansion in methanol is significantly greater than in CO,. Volume ex
