Abstract: The prodn. of radiation-curable acrylates (I) comprises (1) reacting hydroxy cpds. (II) with (meth)acrylic acid and (2) reacting the prods. with epoxide(s) (III); cpds. with one or more prim. or sec. amino gps. (IV) are added in or before stage (2), which is then continued until the acid no. of the mixt. has decreased by at least 3 mg KOH/g from its value at the time of addn. of (IV). Also claimed are acrylates (I) obtd. by this process.

Abstract: Sulphonium salts of formula (I), (II) or (III), or polymeric sulphonic salts contg. repeat gps. of formula (IV) are new; where R1 = H or 1-4C alkyl; R2, R3 = monovalent 5-8C aromatic ring system, opt. contg. heteroatoms and opt. substd. with 5-15C aryl or aryloxy, 1-10C alkyl or alkoxy, halo, OH, or amino gps. or with OH or amino gp.-contg. 5-15C aryl or aryloxy or 1-10C alkyl or alkoxy gps.; R4 = as for R2/R3, or also 1-20C alkyl or alkaryl; R5, R6 = bivalent gps. corresp. to R2 and R3; X = counter-ion. Producing these salts, comprises reacting aromatic mono- or di-thiols with aromatic mono- or di-ethynyl cpds. and converting the resulting sulphides into salts with an alkylating or arylating agent. Pref., R1 = H, R2 and R3 -= phenylene, opt. substd. with one or two 1-6C alkyl gps., R5 and R6 = as for R2 and R3, R4 = Ph (opt. substd. as above) or 1-8C alkyl or 7-15C alkaryl; X = e.g. BF4, FeCl4, PF6, CF3SO3 etc.. Pref. arylating agent (stage 2) is e.g. Ph2IBF4. Amt. of salt is 0.2-5 wt.% w.r.t. polymerisable cpds.. USE/ADVANTAGE - Used as photoinitaotors for cationic polymerisation (claimed). Also claimed are copolymerisable sulhonium salts obtd. by reactin of the above salts (in which at least one of the gsp. R2-R6 contains an amino or OH gp.) with cpds. contg. copolymersable ethylenic gps.. Also claimed are radiation-curable materials contg. the claimed salts. The claimed cpds. overcome the disadvantages of prior-art sulphonium salt photoinitiators (yellowing of polymer film, loss of activity due to the absorbance of decompsn. prods. in the 240-250 nm range); applications include cationic polymerisation of vinyl ethers or epoxides with the aid of UV or electron beam radiation, and the prodn. of photoresists and structured polymer layers.
