摘要：A method for the production of a temperature regulating polyurethane gelcomposition and corresponding articles includes fatty acid esters as a phase changematerial (PCM) directly incorporated in the fluid phase of a polyurethane gel withoutencapsulation. The liquid or melted PCM is solved in the polyol component of the geland is able to crystallize and melt within the gel structure reversibly. The polyurethanegels are under-crosslinked and include an at least nominal three functional ethyleneoxide-comprising alkylene oxide polyether polyol with 0 to 40% EO and an isocyanatewith an effective functionality of from 1.5 to 3.5. The gels are useful in articles where thegel can be positioned close to the human body for temperature regulating purposes,and especially to improve the sleeping comfort of a resting person.
