| abstract | New imidyl cpds. have the formula (I): (in which n = 1 or 2. R1 and R1' independently are 1-4C alkyl or together an opt. Me-substd. tri- or tetra-methylene gp. Y is 1-20C alkylene, opt. contg. heteroatoms, 5 or 6C cycloalkylene, 6-10C arylene, -C6H4-Q-C6H4- (in which Q is a direct bond, NH-, -O-, -CH2-, -CMe2- or -OCO-) or 7 or 8C aralkylene or alkylarylene. If n = 1, X is -NH-CO-alkenyl, -C6H3R2R3, -C6H3(COR4)2, x = 0 or 1. A is alkenyl or (CH2)2COQ R9R8R-7Si If n = 2, X is halogen-COOH, -COOM, -COO-alkyl, -CN,-COO -alkenyl, -O-alkenyl, -OCO-alkenyl, -NH-alkyl, -NH-alkenyl, -NH-CO-alkenyl, -SH, -S-alkenyl If Y is cycloalkylene, arylene, aralkylene, alkylarylene or C6H4-Q-C6H4-, X can also be OH or NH2. R2 and R3 independently are OH or NH2. Both R4 are OH, 1-12C alkoxy, opt. substd. phenoxy, -OM or one R4 is OH and the other R4 is -O-(CH2)q-OCO-CQ1=CH2. R5 is OH, Cl, 1-12C alkoxy, opt. substd. phenoxy or -OM. Both R6 are the same as R4 or together are -O-. R7 and R8 independently are H, OH, Cl, -O-alkyl, -O-phenyl, -OCO-alkyl, -OCO-phenyl, -NH- alkyl or -N-(alkyl)2. R9 is -CH=CH2, Me, Ph or -O-SiMe3 or the same as R7 and R8; or R7 and R8 together are -(OSiMe2)m-O-. M is an alkali metal or 3-24C trialkylammonium cation. Z is linear or branched 1-12C alkylene. Q1 and Q2 are H or Me. m = 2,3 or 4 q = 2 or 3. The alkyl gps. have 1-8C and the alkylene gps 2-4C). (I) are used for the prodn. of photocurable polymers, e.g. polyesters, polyamides, polyamide-imides, polyimides, polyester-polyamides, polyesteramide-imides, polyethers, polyamines, gelatins, polysaccharides and polysiloxanes. (I) can be prepd. by reacting an amine with an anhyd; or if (Y)n-1 is 1-12C alkylene and X is an epoxy gp., by reacting an alkali metal imide with a halohydrin. E.g. 126g (1 mole) dimethylmaleic anhydride were reacted with 115g (1 mole) 4-aminocyclohexanol for 30 min. at 120-125 degrees C, giving 115g (70%) N(-4-hydroxycyclohexyl)-dimethylmaleimide. |
