Abstract: The invention relates to tetrahydrofuran derivatives of the formula (I) in which the radical R1 has the definition (CH2═CH—CO—O—(CHR3—CH2—O)m—CH2)— and the radical R2 has the definition (CH2═CH—CO—O—(CHR4—CH2—O)n—CH2)—, in which the radicals R3 and R4 independently of one another are hydrogen or methyl, and with the proviso that the sum of the indices m and n is a number in the range from 0 to 20.The compounds (I) are suitable for coating the surfaces of solid substrates, more particularly for coating plastics.
