The present invention provides a thermally decomposable binder that achieves a reduced residual carbon after sintering, and that can be subjected to a dewaxing treatment at a relatively low temperature in a non-oxidative atmosphere. More specifically, the present invention provides an aliphatic polycarbonate that has a structure obtained by neutralizing a Br&#xf8;nsted acid with an organic onium salt in a side chain.

Aliphatic polycarbonate and binder resin composition containing said polycarbonate

A pressure sensitive adhesive sheet is provided which comprises a pressure sensitive adhesive layer formed of a pressure sensitive adhesive composition. The pressure sensitive adhesive composition contains an aliphatic polycarbonate and a pressure sensitive adhesive resin other than the aliphatic polycarbonate. The pressure sensitive adhesive sheet can be reduced in the adhesive strength at desired timing by a novel mechanism of action so that the release of an adherend becomes easy. The above pressure sensitive adhesive composition preferably contains an acid/base generator that generates an acid or a base by applying energy.

The present invention relates to a production method of polyalkylene oxide particles including a step of forming the polyalkylene oxide particles by polymerization of an alkylene oxide in a polymerization solution containing a polymerization solvent and a catalyst dispersed in the polymerization solvent. The average particle diameter of the catalyst is 25 &#x3bc;m or less.
