| abstract | 1479567 Organo-silicon compounds DAI NIPPON PRINTING CO Ltd and SHINETSU CHEMICAL CO Ltd 23 Dec 1975 [28 Dec 1974] 52631/75 Headings C3S and C3T An organosilicon compound having one or more units represented by the average formula wherein R<SP>1</SP> is a monovalent heterocyclic group, a monovalent aromatic group or a nitro-, alkoxy-, or halogen-substituted aromatic group, R<SP>2</SP> is a hydrogen or halogen atom, a cyanogroup or a monovalent hydrocarbon group, R<SP>3</SP> is a divalent hydrocarbon group having 1 to 10 carbon atoms, R<SP>4</SP> is a monovalent hydrocarbon group, X is a hydroxy group or hydrolizable atom or group, a is zero or one, b has a value not exceeding 1, c and d are each zero or have values not exceeding 3 and b+c+d has a value not exceeding 4, may be prepared by a method which comprises reacting a maleic anhydride derivative having the general formula wherein R<SP>1</SP> and R<SP>2</SP> are as previously defined, with an organosilicon compound having one or more units expressed by the average formula wherein R<SP>3</SP>, R<SP>4</SP>, X, a, b, c and d are as previously defined and b + c + d has a value not exceeding 4. The reaction may be carried out using a molar ratio of maleic anhydride derivative to organosilicon compound of from 0À1 to 2 : 1, in the presence of a solvent, e.g. xylene, dimethylformamide, tetrahydrofuran or a mixture of toluene and dimethylformamide and a catalyst, e.g. a tertiary amine or an aliphatic or aromatic acid anhydride. Suitable maleic anhydride derivatives are the phenyl, tolyl, naphthyl and their halogen substituted derivatives, thienyl, furyl or pyridyl group substituted maleic anhydrides, Suitable organosilicon compounds of Formula III are, where.b+c+d is less than 4, organopolysiloxanes containing 3-aminopropyl or N- aminoethyl-3-aminopropyl groups or where b+c+d is equal to 4, are silanes, e.g. 3-aminopropyltriethoxysilane, 3-aminopropylmethyldimethoxysilane or N-aminoethyl-3-aminopropyl trimethoxysilane. Maleimido-group containing compounds having the average general Formula I which also contain alkoxy or hydroxy groups may be modified by dehydration or dealcoholation, e.g. they may be modified by a dealcoholation reaction with hydroxy-terminated dimethyl polysiloxane to give a polysiloxane containing maleimido-group. The maleimido-group containing organosilicon compounds are readily cured and hardened by exposure to light, e.g. ultraviolet light without addition of photosensitizers although organic peroxides may be added to increase the curing velocity. |
