Abstract
Described herein are organoborane polymers and methods for the oxidation of these organoborane polymers to poly (vinyl alcohol) PVA. The organoborane polymers of the present invention respond to an external trigger by changing from a hydrophobic to a hydrophilic state.
Claims1
An organoborane copolymer having a structure selected from the group comprising formula 3, 4, or 5
- wherein n is an integer from 1 to 1000;
- wherein m is an integer from 1 to 1000;
- wherein R1 is selected from the group consisting of H, alkyl, alkenyl, alkynyl, aryl, arylalkyl, cycloalkyl, trialkylsilyl, and a halide group;
- R2, R3, R4, R5, R6, and R7 are selected from the group consisting of H, alkyl, alkenyl, alkynyl, aryl, arylalkyl, C3-12 cycloalkyl, trialkylsilyl, and a halide group;
- and R13 is selected from the group consisting of H, aryl, alkyl, carbonyl, CN, and a halide;
- and stereoisomers thereof;
- and
- wherein r indicates a random/statistical copolymer structure;
- b indicates a block copolymer structure;
- and Formula 5 is an alternating copolymer structure.
