    Abstract: Copolymers of formula (I), based on dicarboxylic acid imides, alkenyl isocyanates and/or alkenyl urethanes are claimed, as are also (i) prepn. of (I) by free radical polymerisation of 30-70 mol.% monomer of formula (III) corresp. to the `b' units and 70-30 mol.% cyclic monomer of formula (IV) corresp to the `c' units, opt. with up to 50 mol.% comonomer, the copolymer thus obtd. then being reacted with H-X-Y-Z; and (ii) use of (I) in non-linear optics. In formulae (I), (III) and (IV), R -R = H or 1-20C alkyl (opt. substd. and/or opt. contg. a heteroatom); R = H, 1-10C alkyl (opt. substd. by Ph or OH), phenyl or benzyl (each opt. substd. by one to four 1-6C alkyl or alkoxy gps), 3-8C cycloalkyl, phenylethyl, diphenylmethyl, naphthyl, carbazoyl, isobornyl, adamantyl or 9-fluorenyl; X = O or NH; Y = 1-20C alkylene, (-CH2O)n-, -(CH2CH2O)n- or -(CH2CH(Me)O)n-, with n = 1-15; Z = H or an opt. substd. residue D with nonlinear optical (NLO) properties; M = comonomer; a and c = 0.3-0.7; and b and d = 0-0.3, with a+b+c+d = 1.

    Abstract: 2-Dicyanomethylene-thiazole methine dyes of formula (I) are new. In formula (I), R = H or an opt. substd. 1-10 C alkyl or phenyl gp.; X = N, CQ , CH-CQ -CH, CH=CH-CH=CH-CH or a gp. of formula (IIA) or (IIB), where Q = H, 1-4C alkyl, Cl or Br; Q = H or 1-4 C alkyl; and Y = the residue of the aniline, aminonaphthalene, indole, aminoquinoline, aminothiazole or aminothiophene series; with the proviso that x does not = CH if R = phenyl and Y = a residue of the aniline series. Also claimed are certain 2-dicyanomethylene-4-phenyl-thiazoles used as starting materials for (I). Pref. in (I), Y = the residue of the aminonaphthalene, aminoquinoline or esp. the aniline series; R = 1-6 C alkyl or phenyl, opt. substd. by OH or (meth)acryloyloxy; X = N, CH, CH-CH-CH or CH-CH-CH=CH-CH. (I) can be prepd. by well-known methods.(I) (where L = CQ , CH-CQ -CH, CH=CH-CH=CH or a (IIA) or (IIB) gp.) can be prepd. by reacting an aldehyde Y-L=O with a 2-dicyanomethylene-4-R-substd.-thiazole (III). (I) (where L = N) can be prepd. by condensation of nitroso cpds. of the formula Y-NO or oxidative coupling of amino cpds. of the formula Y-NH2 with (III). (III), including (IIIA), are prepd. by reacting ketones of the formula Hal-CH2-CO-R (hal = halogen) with NH4CNS and malodinitrile. (I) and (III) (R = hydroxyphenyl), including (IIIA; W = H can be prepd. by aq. alkaline hydrolysis of the substd. cpds. (R = alkanoyl-oxyphenyl), including (IIIA; W = 1-6 C alkanoyl).
