Abstract
A process for manufacturing a novel resin which comprises reacting, in the presence of a Friedel-Crafts catalyst, an aliphatic monovalent alcohol with a Diels-Alder addition product, the product being at least one compound having the formula ##SPC1## Wherein each of R.sup.2, R.sup.3, R.sup.4 and R.sup.5 is a hydrogen atom or methyl group, each of R.sup.6, R.sup.7, R.sup.8 and R.sup.9 is a hydrogen atom or alkyl group having 1 to 4 carbon atoms, X is --COOH, --COOR.sup.a, --CN or CONH.sub.2, R.sup.a being an alkyl group having 1 to 4 carbon atoms, A is --CH.sub.2 -- or --CH.sub.2 CH.sub.2 --, and m is an integer of 1 or 2.
Claims25
A process for manufacturing novel resin which consists essentially of reacting in the presence of Friedel-Crafts catalyst a Diels-Alder addition product with an aliphatic alcohol having the formula of
- R.sup.1 OH
- wherein R.sup.1 is an aliphatic straight-chain or branched-chain saturated hydrocarbon group having 1 to 18 carbon atoms or alicyclic hydrocarbon group having 5 or 6 carbon atoms and having or not having a substituent of an alkyl group having 1 to 12 carbon atoms;
- said Diels-Alder addition product being at least one species selected from the group consisting of (a) compounds having the formula of ##SPC9##
- wherein each of R.sup.2, R.sup.3, R.sup.4 and R.sup.5 is a hydrogen atom or methyl group, each of R.sup.6, R.sup.7, R.sup.8 and R.sup.9 is a hydrogen atom or alkyl group having 1 to 4 carbon atoms, X is --COOH, --COOR.sup.a, --CN or CONH.sub.2, R.sup.a being an alkyl group having 1 to 4 carbon atoms, A is --CH.sub.2 -- or --CH.sub.2 CH.sub.2 --, and m is an integer of 1 or 2, and (b) compounds having the formula of ##SPC10##
- wherein R.sup.2, R.sup.3, R.sup.4, R.sup.5, X, A and m are the same as defined above.
