"FOTOINICIADORES DE POLISSILOXANO TENSOATIVOS". A presente invenção refere-se a fotoiniciadores poliméricos da fórmula I ou II onde n e m independentemente um do outro são 3-5; o é 10-16; p é 4-8; R é fenil-CO-CO-O-; Y e Y independentemente um do outro são C~ 1~-C~ 10~ alquileno ou ¢(CH~ 2~)~ a~-O-(CH~ 2~)~ b~!~ c~- onde a é 2-10, b é 0-10, c é 1-3; com a condição de que, no entanto, eles sejam pelo menos 1 se o grupo metileno em questão estiver entre dois átomos de oxigênio. Polymeric photoinitiators of the formula I or II wherein n and m independently of one another are 3-5; o is 10-16; p is 4-8; R is phenyl-CO-CO-O-; Y and Y' independently of one another are C1-C10alkylene or -[(CH2)a-O-(CH2)b]c- wherein a is 2-10, b is 0-10, c is 1-3; with the proviso that they are, however, at least 1 if the methylene group in question is between two oxygen atoms.
