    摘要： An unsaturated polyester resin composition comprising an unsaturated polyester resin, a polymerizable monomer and a mixture of block copolymers having acid groups prepared by first copolymerizing in a first copolymerization reaction a polymeric peroxide with a monomer A or B, or with an unsaturated acid together with monomer A or B, thereby obtaining a copolymer having peroxy bonds in the molecule thereof, which copolymer is further copolymerized in the second copolymerization reaction with each of monomers A or B or the unsaturated acid which were excluded in the first copolymerization reaction to give the block copolymer mixture, which composition shows no segregation of the low shrinkage agent on thickening by a thickener and the said composition gives cured moldings of reduced shrinkage which are excellent in many characteristics.Monomer A: a vinyl acetate or a mixture of vinyl acetate and one or more monomers which are copolymerizable with vinyl acetateMonomer B: styrene series monomers, unsaturated organic acids, anhydrides, or acid esters, or mixtures thereof

    摘要： Alkoxyamines containing a vinyl group as represented by the following general formula (1) are produced in a method which comprises a process of heating divinyl benzene, nitroxide compound and organic peroxide up to a temperature at which the organic peroxide decomposes thermally: (In the formula, R1 represents an aryl group or an R2O group, wherein R2 represents a linear or branched alkyl group having 1-12 carbon atoms or a cycloalkyl group. R3 and R4 are each tertiary alkyl group having 4-6 carbon atoms or of cyclic structure where R3 and R4 are connected with each other having a total carbon number of 8-16. In case of cyclic structure, they are optionally substituted either by an alkyl group, an oxo group, a hydroxyl group, an acyloxy group or an alkoxy group.) Furthermore, graft polymers can be produced by the use of high molecular radical polymerization initiators from which an alkoxyamine group suspends.
