DETAILED DESCRIPTION OF THE DRAWINGS FIG.
2 is the GLC profile for the reaction product of Example I(B).
The peak indicated by reference numeral "20" is the peak for the isocyclocitral reactant defined according to the structure: ##STR39## The peak indicated by reference numeral "21" is the peak for the reaction product containing the compounds defined according to the structures: ##STR40## with a preponderance of the compound having the structure: ##STR41## Referring to FIGS.
14 and 15, which show the apparatus for preparing scented polymers such as polyethylene, a quantity of thermoplastic polymer having a melting point of 220.
degree.
-250.
degree.
F.
is placed in a container 512 as illustrated in FIGS.
14 and 15.
25 Pounds of a perfume formulation containing at least one of the cyclohexenyl-alpha-alkyl acrelein derivatives of our invention is then quickly added to the liquified molten polymer in container 512, the lid 528 is put in place and the agitating means 573 are actuated.
The temperature is maintained at about 225.
degree.
F.
and the mixing is continued for about 5-15 minutes.
The valve "V" is then opened to allow flow of the molten thermoplastic polymer (e.
g.
, polyethylene) enriched with a scent-imparting substance containing at least one of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, to exit through orifices 534.
The liquid falling through orifices 534 solidifies almost instantaneously upon impact of the moving cooled converyor 538.
Thermoplastic polymer (e.
g.
, polyethylene) beads or pellets 544 having a pronounced scent as described in the examples, infra resulting from the composition containing one of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention are thus formed.
Analysis demonstrates that the pellets contain about 25% of a scent-imparting material containing one of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention so that almost no lost is in the scenting substance occur.
The pellets are used as set forth, infra
