Hydrolysable and polymerisable silane(s) with thiol substit. - prepd. from silane and oligo-thiol, useful for thiol-ene poly-addn. and preparing polycondensate. e.g. for adhesive or coating compsns.
Hydrolysable and polymerisable silane(s) with thiol substit. - prepd. from silane and oligo-thiol, useful for thiol-ene poly-addn. and preparing polycondensate. e.g. for adhesive or coating compsns.
Silanes have the general formula (I): [(HS-R5)nR6-S-E-R5]aSiXxR4-a-x3 (I); E = -CO-NH-, -CS-NH-, -CH2-CH2- or -CH2-CH(OH)-;R3 = 1-15 C alk(en)yl, (alkyl)aryl or arylalkyl; R5, R6 = 1-15 C alkylene or arylene(alkylene); R3, R5, R6 may contain O or S atoms or ester, carbonyl, amido or amino gps. in the chain; X = H, halogen, OH, alkoxy, acyloxy, alkylcarbonyl, alkoxycarbonyl or NR"2; R" = H, alkyl or aryl; a, x = 1, 2 or 3; and n = 2, 3, 4 or 5.
