Abstract: THE DISCLOSED INVENTION RELATES TO IMPROVED OPAQUE FILMS WHICH ARE CONTINUOUS, MICROCELLULAR AND NON-POROUS POSSESSING UNUSUAL HIDING ABILITY AND OPACITY. THE FILMS OF THIS INVENTION ARE PREPARED FROM A NOVEL LATEX MIXTURE COMPRISING: NON-ELASTOMERIC POLYMERIC MATERIAL, WATER, NON-SOLVENT FOR THE POLYMERIC MATERIAL IN A WEIGHT RATIO OF NON-SOLVENT TO POLYMER SOLIDS OF ABOUT 0.05 TO ABOUT 3:1.0 AND AN OPACIFYING PIGMENT IN A WEIGHT RATIO OF PIGMENT TO POLYMER SOLIDS OF FROM ABOUT 0.1 TO ABOUT 5:1. THE NON-SOLVENT IS SELECTED SUCH THAT IT HAS A BOILING POINT RANGE ABOVE THAT OF WATER AND HAVING SUFFICIENTLY LOW VOLATILITY TO REMAIN ENTRAPPED IN THE POLYMERIC MATRIX WHEN THE COMPOSITION HAS REACHED A QUASI-RIGID OR TACKFREE STATE WHEN APPLIED AS A FILM. ONCE THE FILM HAS BECOME TACK-FREE THE NON-SOLVENT IS EVAPORATED SO AS TO LEAVE BEHIND MINUTE, CLOSED CELLS WHICH ENHANCE THE HIDING AND OPACITY OF THE FILM. THE DISCLOSED INVENTION ALSO RELATES TO OPAQUE FILMS WITH ENHANCED OPTICAL PROPERTIES PRODUCED BY THE INCLUSION OF COLORED PIGMENTS, DYES FLUORESCENT MATERIALS AND OPTICAL BRIGHTENERS IN THE UNUSUALLY OPACIFIED FILMS IN SUCH A MANNER AS TO MAXIMIZE THEIR EFFECTIVE NESS THEREIN.

Abstract: A solid-phase synthesis carrier, a preparation method therefor and the use thereof, wherein a diene cross-linking agent with a similar reactivity ratio to styrene and two vinyl groups thereof not on the same benzene ring is selected as a cross-linking monomer, and is subjected to suspension polymerization to obtain a porous resin. The porous resin is then functionalized to obtain a porous resin with an amino or hydroxyl functional group. Compared with existing preparation methods, the reactivity ratio of the cross-linking agent and styrene is similar, which is beneficial to improving the uniformity of the chemical structure in the resin, forming uniformly distributed active sites and channels, and is beneficial to improving the reaction efficiency and reducing the mass transfer resistance. The preparation of oligonucleotides by using such a carrier as a solid-phase synthesis carrier can improve the yield and purity of the oligonucleotides.
