The segment of a solar collector comprises a top side, a bottom side and a circumferential end face having at least one longitudinal side, wherein the longitudinal side forms a top edge with the top side and forms a bottom edge with the bottom side, and comprises a core structure having at least one core made of foamed material. The segment of a solar collector further comprises a shell made of one or a plurality of layers of a fiber material, wherein the shell at least partially covers the top side, the bottom side and at least the longitudinal side of the circumferential end face, wherein at least one layer of the shell extends about the top edge and at least one layer of the shell extends about the bottom edge, and a reflection layer disposed on the top side.

The invention relates to novel isocyanates containing tertiary amino groups, a process for preparing them, and also their use for the synthesis and modification of polymers. The invention provides isocyanates of the formula (I) where R1 and R2 are, independently of one another, alkyl having from 1 to 6 carbon atoms, where R1 and R2 may be joined to form a ring, Z is alkylene having from 2 to 6 carbon atoms, n is an integer from 0 to 20, Y is alkylene having from 2 to 6 carbon atoms. The alkyl radicals R1 and R2 may be linear or branched or joined to form an aliphatic ring. The alkylene radical Z preferably contains from 2 to 4 carbon atoms.
