果たし得なくなるおそれがあった。[Prior Art] Conventionally, rain gutters are generally made of extruded hard vinyl chloride, but hard vinyl chloride has a large coefficient of linear expansion of 7.0 x 10-5 (1/°C), so it expands and contracts when heated. is large. Therefore, when hard PVC rain gutters are attached to a building along with joints, changes in seasonal temperatures and temperature differences between day and night can cause the rain gutters to expand and contract due to heat, causing them to pull out of the joints or become thermally deformed, resulting in cracks. There was a risk that the rain gutter would no longer function as a rain gutter.

The amount of acrylic monomer added when making a paste is 80 to 2 parts by weight per 100 parts by weight of vinyl chloride resin.
00 parts by weight is appropriate. If it is less than 80 parts by weight, a paste with a viscosity suitable for impregnation cannot be obtained, and if it exceeds 200 parts by weight, the amount of acrylic monomer is too large and a B-stage prepreg sheet cannot be obtained.

Since the layers laminated on both sides are made of vinyl chloride resin, the two are integrally bonded. In addition, since the core material is a fiber-reinforced acrylic crosslinked vinyl chloride resin, it has low thermal elasticity, high heat distortion temperature and high glass transition temperature, excellent heat resistance, and high rigidity.
