BLOCK COPOLYMERS PREPARED FROM 2-SUBSTITUTED-$2-OXAZOLINES AND 2-SUBSTITUTED-5,6-DIHYDRO-4H-1,3-OXAZINES ARE EXCELLENT ANTISOILANTS FOR A WIDE VARIETY OF SUBSTRATE MATERIALS. THESE BLOCK COPOLYMERS ARE PREPARED BY FIRST HOMOPOLYMERIZING EITHER OXAZINE OR OXAZOLINE MONOMER; THEN THE OTHER MONOMER IS ADDED TO THE FIRST-FORMED BASE POLYMER. THE SECOND MONOMER WILL ADD ON TO THE END OF THE FIRST-FORMED BASED POLYMER AND HOMOPOLYMERIZE, THEREBY FORMING BLOCK COPOLYMERS CONSISTING ESSENTIALLY OF JOINED OXAZINE AND OXAZOLINE HOMOPOLYMER CHAINS. A SURFACE COATING OF THESE BLOCK COPOLYMERS SIGNIFICANTLY INHIBITS SOILING OF THE COATED SUBSTRATE. ALSO, WHEN DEPOSITED ON THE SURFACE OF, OR INCORPORATED INTO A SUBSTRATE, THE BLOCK COPOLYMERS ARE EFFECTIVE ANTISTATS. |
