Abstract: Polymer-based adhesives are claimed, contg. 0.2-80 wt%(w.r.t. polymer) of oligopropene derivs. of formula (I), (II) or (III) (where n = 0-100; X = a gp.) with a mol. wt. of less than 300 contg. at least one copolymerisable olefinic double bond or a reactive H atom. Also claimed are substrates coated with these adhesives. Pref. the polymer has a Tg of -50 to+40 deg C and contains 1-65 wt% (I-III). Pref. polymer is obtd. by polymerisation of (a) 20-99.8 wt% 1-10C alkyl (meth)acrylate, vinyl 1-20C carboxylate, up to 20C vinylaromatic, unsatd. nitrile, vinyl halide, 1-10C alkyl vinyl ether and/or 2-8C aliphatic mono- or di-olefin as main monomer, (b) 0.2-80 wt% (I), (III) or unsatd. oligomer (II) and (c) 0-50 wt% other comonomers; or a mixt. of 50-99.8 wt% (a) and 0.2-50 wt% (c) is polymerised first and then reacted with oligomer (II) contg. a reactive H atom.

Abstract: Radically-curable reactive adhesives (I) are based on olefinic monomers (II) contg. soluble or dispersible rubbery polymers (III) and radical-forming polymerisation initiators; the novelty is that 1-80 wt.% of (II) consists of N,N',N''-tris(methacryloyl-oxyethyl)-isocyanurate (IV). Pref., 2-30 wt.% of (I) consists of glass microspheres, surface-modified with reactive organic gps. (V). Pref. (I) contain 60-85 wt.% alkyl (meth)acrylate (e.g. n-Bu, 2-ethylhexyl, etc.), vinyl acetate, styrene, acrylonitrile, etc. (II), butadiene copolymer rubber, etc. (III), with benzoyl or other peroxide and reducing agent as initiator system. USE/ADVANTAGE - W.r.t. prior-art reactive adhesives, (I) have improved adhesive properties, esp. tensile shear strength and stability at high temp. (e.g. above 100 deg.C.).
