Abstract

trata-se de tensoativos de copolímero de siloxano-oxialquileno em combinação com ésteres alquílicos de ácidos graxos. os ésteres alquílicos de ácidos graxos são representados pela fórmula geral z-coo-y, em que z é um grupo c10-24 alquila ou alquileno saturado ou insaturado e y é tipicamente um grupo c1-6 alquila, alquileno linear ou ramificado. os tensoativos de copolímero de siloxano-oxialquileno que são tipicamente usados com os ésteres graxos têm a fórmula geral mdxd'ym, em que m representa (ch3)3sio1/2 ou r(ch3)2sio1/2, d representa (ch3)2sio2/2, d' representa (ch3)rsio2/2, e o valor de x+y é de 50 a 220, e a razão x/y é de 5 a 15 inclusiva. nas fórmulas acima para m e d', r é um substituinte que contém poliéter. os tensoativos de copolímero de siloxano-oxialquileno usados em conjunto com o éster graxo contêm uma fração principal (60 a 80% em peso) de siloxano-oxialquileno com um r pendente tipicamente definido como porções químicas de cnh2no(c2h4o)a(c3h6o)br? que têm pesos moleculares ponderais médios de cerca de 1.400 a 2.000, e em que n é 1 a 4 e tipicamente 3, os valores de a estão na faixa de 12 a 22 e tipicamente 16 a 20 e os valores de b estão na faixa de 12 a 22 e tipicamente 16 a 20, em que r? representa tipicamente o grupo acila -c(o)ch3. o tensoativo da invenção também contém uma fração menor de um copolímero de siloxano-oxialquileno (6 a 10% em peso) que tem dois rs pendentes tipicamente definidos como porções químicas de cnh2no(c2h4o)a(c3h6o)br? que têm pesos moleculares médios de cerca de 1.000 a 3.500, e em que n é 1 a 4 e tipicamente 3, os valores de a estão na faixa 8 a 40 e tipicamente 10 a 35 e os valores de b estão na faixa de 8 a 40 e tipicamente 10 a 35, em que r? representa tipicamente o grupo acila c(o)ch3.
