Abstract:
A branched polyene compound represented by the formula ##STR1## wherein f is an integer of 1-5; R.sup.1 and R.sup.2 represent hydrogen atoms or alkyl groups of 1-5 carbons; R.sup.3 represents a hydrogen atom or an alkyl group of 1-5 carbons or an alkenyl group represented by the formula ##STR2## wherein n is an integer of 1-5; R.sup.4, R.sup.5 and R.sup.6 represent hydrogen atoms or alkyl groups of 1-5 carbons; all of R.sup.1, R.sup.2, R.sup.3 are not simultaneously hydrogen atoms; and all of R.sup.4, R.sup.5 and R.sup.6 are not simultaneously hydrogen atoms.
