    Abstract: Free-radical-crosslinkable copolymers having a number average molecular weight of from 1500 to 6000 and a molecular weight distribution corresponding to a polydispersity of from 1 to 4.0, obtainable by polymer-analogous reaction of A) a copolymer (A) comprising a1) from 50 to 85 mol % of a monomer (a1) containing the methacrylic acid structural unit and a2) from 15 to 50 mol % of another free-radical-polymerising monomer (a2), where a3) from 5 to 50 mol % of the total amount of the monomers (a1) and (a2) are monomers (a3) carrying functional groups which are capable of a condensation or addition reaction, obtainable by a free-radical bulk or solution polymerisation at from 140 to 210 DEG C and a mean residence time of from 2 to 90 min, with B) an olefinically unsaturated monomer (B) carrying a functional group which is complementary to that of the monomers (a3). The free-radical-crosslinkable copolymers are used as binders for powder coatings (paints).

    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.
