The present disclosure provides a two-component solventless adhesive composition comprising a polyol component and an isocyanate component. The polyol component comprises a phosphate functional compound, and at least one polyol selected from polyester, polyether, and the combination thereof; and the isocyanate component comprises isocyanate prepolymer that is the reaction product of at least one isocyanate monomer and at least one polyol selected from polyester, polyether, and the combination thereof.

The present invention relates to a polymer comprising repeating units consisting of a substituted pyrrole ring. In particular, the repeating units consist of substituted pyrrole containing polar groups capable of interacting with carbon allotropes such as carbon nanotubes, graphene or nanographites, in order to improve the chemical-physical characteristics of the allotropes mainly by increasing their dispersibility and stability in liquid media and in polymer matrices. The invention also relates to products of addition of these polymers with carbon allotropes in order to obtain easily dispersible macromolecules.

Methods of printing a three-dimensional object using co-reactive components are disclosed. Thermosetting compositions for three-dimensional printing are also disclosed.

A component comprising a first outer region (11), at least one intermediate region (13) and a second outer region (12). The outer regions (11, 12) have a higher density and/or a higher elastic modulus than the at least one intermediate region (13). A polymer composition (21) can, preferably, be injected into the component (1) such that a mechanical connection (41) is fixed or can be fixed in the polymer composition (21).

Processes are described for producing an aromatic diamine-initiated polyether polyol having a measured OH number of 300 to 500 mg KOH/g and a viscosity at 25° C. of 5000 to 50,000 mPas. The processes include a first alkoxylation step in which an alkylene oxide consisting essentially of propylene oxide is reacted with a starter consisting essentially of aromatic diamine at a molar ratio of propylene oxide to aromatic diamine of 1.4:1 to 2.0:1 to form an alkoxylated product; and a second alkoxylation step in which an alkylene oxide consisting essentially of propylene oxide is reacted with the alkoxylated product, in the presence of an added catalyst, until the ratio of moles of propylene oxide added in the process to the moles of aromatic diamine added in the process is 4:1 to 9:1.
