The invention relates to a heterogeneous method for oligomerising alkenes in order to produce hydricarbons within a diesel fraction in the present of a catalyst based on the ITQ-39 zeolite. The oligomerisation method described in the present invention includes at least: a. feeding a catalyst containing at least the ITQ-39 zeolitic material into the reactor; b. supplying the reactor with a stream that includes at least one olefinic compound; and c. enabling the catalyst containing at least the ITQ-39 material and the organic compound to remain in contact during the time required for the reaction to take place.
Disclosed are a composition for a urethane-base plastic lens, comprising:
(a) at least one ester compound selected from isocyanate compounds, isothiocyanate compounds and isocyanato-containing isothiocyanate compounds,
(b) at least one active hydrogen compound selected from hydroxyl compounds, mercapto compounds and mercapto-containing hydroxyl compounds,
(c) a tertiary amine, and
(d) a Lewis acid;
a plastic lens obtained by heating and curing the composition, and a process for the production of the plastic lens. This composition has a long pot life and can produce an optically uniform plastic lens in a short time.
