Abstract: In a process for producing a float plate glass having a plate thickness falling within a range from 0.1 mm to 2 mm, the process includes a step of draining a surface portion of a melted glass base material from an inside of a forming furnace or a glass-material melting furnace, in a region upstream from a location at which a width of glass ribbon is adjusted by top rolls.

Abstract: A flame-retarding resin composition consists essentially of (A) a graft copolymer obtained by bulk and suspension-polymerizing an aromatic monoalkenyl monomer and a vinylcyano monomer and/or a monomeric alkyl ester of acrylic acid or methacrylic acid in the presence of a diene type rubber component, as an optional ingredient (B) a graft copolymer obtained by emulsion-polymerizing a monomeric mixture of the above mentioned monomers in the presence of a diene type rubber latex, (C) a chlorinated polyethylene having a degree of chlorination of 25 to 45 wt. %, (D) tetrabromo-bisphenol A or a derivative thereof and (E) antimony trioxide.

Abstract: An impact-resistant resin composition comprises:100 parts by weight of a mixture of graft copolymers consisting of;50-90% by weight of a graft copolymer (A) obtained by polymerizing an aromatic monoalkenyl monomer and a vinyl cyan monomer in the presence of a diene type rubber component first under the bulk polymerization condition and subsequently continuing the polymerization under the suspension polymerization condition to substantially complete the polymerization, and having dispersed therein the rubber of an average particle size in the range of from 0.2 to 0.
