Abstract
Novel compounds of the general formula <FORM:1049326/C2/1> wherein R1 and R2 are each an alkyl group or, together with the C atom to which they are both bonded, represent a saturated carbocyclic ring, R4 is H or an alkyl group and R3 is H or an alkyl group, or the enol form thereof when R4 is H, are prepared by reacting a compound of formula R1(R2)C = C = O with a compound of formula R3-C = C-OR4 in which formula R1, R2 and R3 are as defined in any of claims 1 to 5 and R4 is an alkyl group, or compounds of the first formula above wherein R4 is hydrogen, or the keto form thereof, may be prepared by hydrolysing the corresponding compound wherein R4 is an alkyl group. Compounds of general formula <FORM:1049326/C2/2> wherein R1, R2 and R3 are as defined above and R4 is alkyl are prepared by catalytic hydrogenation of the corresponding compound of the first general formula above. Diesters of dicarboxylic acids with the alcohols of the last general formula above are prepared, e.g. bis-(2,2-dimethyl-3-ethoxycyclobutyl) adipate.ALSO:15 parts of 2-butyl-3-ethoxy-2-ethyl-3-cyclobuten-1-one is milled on heated rolls with 85 parts of cellulose acetate butyrate resin to give a tough plasticized resin with improved moulding properties.
