Title:
TRANSPARENT ANTISTATIC ACRYLIC RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2804976
Kind Code:
B2
Abstract:
PURPOSE: To obtain the subject composition excellent in permanent antistaticity and transparency, and useful for lighting fixtures, equipment nameplates, etc., by blending an acrylic resin with a polyether-ester-amide made from a specific polyamide and polyether diol.
CONSTITUTION: This composition comprises (A) 70-97wt.% of an acrylic resin and (B) 30-3wt.% of a polyether-ester-amide ≤15mJ/mg in the maximum value of the endothermic peak at the higher side melting peak temperature determined with a differential scanning colorimeter, produced by polycondensation between (i) a polyamide bearing carboxyl groups at both ends 400-3300 in number-average molecular weight made from at least one kind of polyamide-forming monomer selected from ≥6C aminocarboxylic acids and ≥6C lactams, etc., and a 6-20C dicarboxylic acid containing ≥5mol% of a dicarboxylic acid having intramolecular cyclic structure and (ii) a polyether diol such as a polyoxyalkylene glycol 300-4000 in number-average molecular weight, and containing 40-80mol% of the component (ii).
