Abstract: The present invention relates to an amino-functional polysiloxane of formula (1) where each R1 is independently selected from alkyl or aryl radicals, each R2 is independently selected from hydrogen, alkyl or aryl radicals, n is selected so that the molecular weight for the functional polysiloxane is in the range of from 400 to 10,000 and R3 is a bivalent radical or —O—R3—NH—R5 is hydroxy or alkoxy, and R5 is selected from hydrogen, aminoalkyl, aminoalkenyl, aminoaryl, aminocycloalkyl radical, optionally substituted by alkyl, aryl, cycloalkyl, halogen, hydroxy, alkoxy, thioalkyl, amino, amino derivatives, amido, amidoxy, nitro, cyano, keto, acyl derivatives, acyloxy derivatives, carboxy, ester, ether, esteroxy, heterocycle, alkenyl or alkynyl and where 0 to 90% of —O—R3—NH—R5 is hydroxy or alkoxy.

Abstract: The present invention relates to an improved structure of a CD storage device comprising a plurality of thick paperboard sheets so as to store large amount of CDs. The surface of each thick paperboard sheet is provided with sealed storage chamber for the storing of CDs. The device allows convenient withdrawal and insertion of CD, and the device can be manufactured with low cost.
