Abstract: An unsaturated polyester resin composition comprising (A) an unsaturated polyester alkyd prepared by condensing all or at least 30 mol% of 1,2-butanediol as a polyhydric alcohol component, all or part of phthalic anhydride as a saturated polybasic acid component, and an unsaturated polybasic acid component, and (B) an unsaturated monomer copolymerizable with component (A), the amount of component (B) being 20 to 55 parts by weight based on 100 parts by weight of component (A) is disclosed. The thus-formed unsaturated polyester resin composition is of low viscosity and is easy in filling with glass fibers, pigments, inorganic fillers, etc. Further, it has such advantages that the smell of the unsaturated monomer is low and that the influence against human beings due to evaporation of the unsaturated monomer can be reduced.

Abstract: Gaseous-phase polymerization of an .alpha.-olefin with a catalyst and without a liquid dispersant is carried out under the following conditions:1. A solid phase comprising said catalyst and particulate olefin polymer is caused principally by mechanical agitation to undergo circulation in the up-and-down directions within a reaction chamber of substantially vertical-cylinder type, a reaction bed being formed by said circulating solid phase;2. The ratio of the diameter to height of said reaction bed is of the order of from 1 : 0.5 to 1 : 3;3. The starting-material .alpha.-olefin is supplied in liquid state into the reaction chamber from a point above the reaction bed and vaporized within the reaction chamber; and4. Heat of polymerization reaction is removed principally by the latent heat of vaporization absorbed by said vaporization of the liquid .alpha.-olefin.
