摘要:
A polylactic acid composition comprising (A) a polylactic acid-series resin and (B) an acrylic triblock copolymer is prepared. The composition fulfills the following requirements: (1) the acrylic triblock copolymer (B) is a triblock polymer comprising (B1) a polymer block having a glass-transition temperature of not higher than 25° C., (B2a) a polymer block which has a glass-transition temperature of not lower than 60° C. and is bound to a terminal of the polymer block (B1), and (B2b) a polymer block which has a glass-transition temperature of not lower than 60° C. and is bound to another terminal thereof; (2) the polymer block (B1) comprises a main structural unit derived from an acrylate, and the polymer block (B2a) and the polymer block (B2b) independently comprise a main structural unit derived from a methacrylate; and (3) both of the weight-average molecular weights of the polymer block (B2a) and polymer block (B2b) are smaller than the weight-average molecular weight of the polymer block (B1). The polylactic acid-series resin (A) and the acrylic triblock copolymer (B) may form a phase separation structure.

摘要:
A transfer-type adhesive material A is obtained by applying a adhesive 1 composed of a adhesive composition 10 (not shown) containing an acrylic polymer or a styrene-based polymer onto a release substrate in an intermittent pattern. The present invention includes pressing a nut N and a washer W as hard articles against the above-mentioned transfer-type adhesive material A, transferring a plurality of dots 1d of the adhesive 1 onto pressed surfaces Na and Wa of the nut N and the washer W, and applying onto a target surface C1b the plurality of dots 1d of the adhesive 1 transferred onto the pressed surfaces Na and Wa.
摘要:
The invention provides a nonwoven fabric comprising fiber primarily formed of a (meth)acrylic-based block copolymer, wherein the (meth)acrylic-based block copolymer is a specific tri-block copolymer. The invention can provide a nonwoven fabric with excellent light resistance, weather resistance, durability, flexibility and stretchability.
摘要:
A relationship information display device comprises a display information generation section, a display control unit, and a display area moving section, and displays the identification mark of no-attention information in which the distance calculated from the relationship strength with attention information is included in a predetermined range that can be changed by the operation of a user. The relationship information display device displays the identification mark of the no-attention information at the position at which the distance from a position serving as a reference is the distance calculated on the basis of the relationship strength between the attention information and the no-attention information in a state in which the position serving as the reference associated with the attention information is fixed even if a display range is changed. The relationship information display device docs not display the identification mark of the no-attention information if the distance associated with the no-attention information is not included in the predetermined range.
