Patent ID: RE41805

Claim:
A moisture curable composition produced by blending: 100 parts by weight of a mixture (A) comprising: (1) a copolymer having reactive silicon groups which can be cross-linked by hydrolysis, whose molecular chain has: (i) alkylacrylate and/or alkylmethacrylate monomeric units having an alkyl group with 1 to 8 carbon atoms; and (ii) alkylacrylate and/or alkylmethacylate monomeric units having an alkyl group with 10 or more carbon atoms; and (2) an oxyalkylene polymer including reactive silicon groups which can be cross-linked by hydrolysis; and 2 parts by weight to 300 parts by weight of polymethyl methacrylate powder (B) having a grain diameter ranging from 0.01 μm to 300 μm , wherein said mixture ( A ) has a first refractive index, and said polymethyl methacrylate powder ( B ) has a second refractive index, and wherein a difference of the first refractive index and second refractive index is 0 . 1 or less .
