Abstract: A blended composition consisting of a thermoplastic olefin resin (Comp. A) with an acrylonitrile-styrene-alkyl acrylate copolymer (Comp. B) was attempted to create substitution for vinyl chloride compound prepared from vinyl chloride resin proper and a plasticizer, but resulted in inferior interdispersibility. Incorporation of a thermoplastic epoxy resin (Comp. C) has brought definite improvement in the interdispersibility. A resinous composition including the components A, B, and C has the utility of substitution for vinyl chloride compounds as well as its products.

Abstract: An epoxidized block copolymer (E) produced by epoxidizing a block copolymer (C) comprising a polymer block (A) mainly made from an aromatic vinyl compound and a polymer block (B) mainly made from a conjugated diene compound or a product (D) of hydrogenation of the copolymer (C) and satisfying at least one of the following requirements (1), (2) and (3): (1) the molar ratio R is 0.001 to 0.1, R being defined by the formula: R = [hydroxyl]/[epoxy] (wherein [hydroxyl] is the number of moles of hydroxyl groups contained per unit weight of the epoxidized block copolymer and [epoxy] is that of epoxy groups); (2) the gel content is 5 wt.% or below; and (3) the chloride ion content is 7 ppm or below. The above copolymer (E) can be produced by epoxidizing the block copolymer (C) or (D) in an organic solvent and removing the solvent by evaporation. Compositions comprising the copolymer (E) and other compounds and/or resins are useful.
