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.

Abstract: A method for the preparation of 2,7-dioxa-bicyclo3.2.1octane - comprises: (a) a butene diol derivative of formula (I) undergoes an addition reaction with a vinyl ether of formula (II) in the presence of a halogenating agent to form an intermediate of formula (III); (b) ring closure of (III) forms a tetrahydrofuran compound of formula (IV); (c) the alcohol ROH is eliminated from (IV) to form a second intermediate of formula (V); and (d) ring closure in (V) takes place to form a 2,7-dioxa-bicyclo3.2.1octane or a derivative of formula (VI): R-O-CH(X')=CH(X) (I) HO-CH)2(Y)-CH(Z)=CH(Z')-CH2(Y')-OH (II) R = hydrocarbon; Hal = halogen; and X - Z` = hydrogen or 1-20 C hydrocarbon.

Abstract: A process for the production of coatings or moulded products by radiation curing, in which radiation-curable materials (I) containing 1-100 wt% compounds (A) with at least one cationically polymerisable 2,3-dihydrofuran (DHF) base unit (based on the total amt. of cationically and optionally radically polymerisable compounds) are irradiated with high-energy light. Also claimed are (i) radiation-curable materials (I), and (ii) compounds with 2 or more DHF units.

Abstract: The invention relates to a process for the preparation of (meth)acrylate polymers containing pendant (side-chain) nonlinear-optical chromophores and having moelcular weights of between 5000 and 5,000,000, in which polymers of (meth)acryloyl chloride are reacted in a polymer-analogous reaction in solution with D- omega -aminoalkyl chromophores of the formula (I) in which D is an electron donor, A is an electron acceptor, R is H, alkyl or cycloalkyl, X are CH groups and/or N atoms and m is from 2 to 11. The polymers prepared according to the invention can be used in optical components.
