Abstract: A heat resistant copolymer composition is provided by blending two kinds of copolymers one of which is obtainable by polymerizing a maleimide monomer (A), an aromatic vinyl monomer (B), an unsaturated nitrile monomer (C) and optionally at least one other comonomer copolymerizable therewith (D) in a specific monomer ratio in the presence or absence of an elastomeric polymer and which has an intrinsic viscosity of 0.3 to 1.2 dl/g, and another of which is obtainable by copolymerizing the aromatic vinyl monomer (B), the unsaturated nitrile (C) and optionally at least one other comonomer copolymerizable therewith (D) in a specific monomer ratio in the presence or absence of the elastomeric polymer and which has an intrinsic viscosity of 0.3 to 1.5 dl/g.

Abstract: A case for a tape, particularly for a bias tape, including a cover and a base plate adhered to the cover. An integral guide extending tangentially from the case has a top wall tapering toward its outlet so that the bias tape will be folded down the middle as it is pulled out of the case.

Abstract: A case for a tape includes a base sheet, a cover fixed onto the base sheet and enclosing a roll of tape therein, and a guide extending from the cover and having an open end for dispensing the tape therethrough. The guide has a bent portion between the cover and the open end, the guide being shaped for first guiding the tape tangentially to the roll of the tape, and then changing its course toward the open end. When the case is for a bias tape it has the guide tapering toward the open end, and a slit extending from the open end toward the cover beyond the bent portion along the guide, thereby further folding down the tape longitudinally as the tape is pulled forward and passed through the guide.
