<p>PURPOSE:To obtain the subject structure capable of efficiently being recycled at a low cost without separately separating and recovering both a lamp lens and a lamp housing by preparing the lamp lens from an acrylic resin and the lamp housing from a thermoplastic resin compatible with the acrylic resin. CONSTITUTION:The objective structure is composed of a lamp lens made of an acrylic resin and a lamp housing made of a thermoplastic resin, which is a resin, compatible with the acrylic resin and capable of providing a composition having >=25kg.cm/cm Izod impact strength (unnotched) and >=10% elongation by melt kneading 50wt.% resin with 50wt.% acrylic resin. A composition composed of (A) a copolymer of styrene and acrylonitrile, (B) a graft copolymer obtained by grafting styrene/acrylonitrile copolymer onto styrene-butadiene rubber and (C) a copolymer composed of respective units of methyl methacrylate, styrene and methacrylic acid and a glutaric acid anhydride ring structure unit expressed by the formula (R1 and R2 are H or CH3), etc., is preferred as the thermoplastic resin.</p> |
