FORFARANDE FOR FRAMSTELLNING AV TREPLASTMATERIAL GENOM TERMISK POLYMERISATION, POLYKONDENSATION OCH KONDENSATION AV MONOMERER I MATERIAL AV TRE

摘要

A thermal polymerization of monomeric materials in a porous workpiece such as wood is carried out using a temperature-controlling or heat-carrying agent. The controlled heat supply for developing the threshold temperature for an exothermic reaction or for supplying the heat for an endothermic chemical reaction and for removal of excess heat in exothermic reactions is effected by water whose addition in small quantities is not detrimental to the workpiece or the reactions.
