Abstract
The invention relates to functionalized polymers including homopolymers and copolymers and their uses in industrial applications and in agricultural applications. In particular, the homopolymers and copolymers may be, for example, used in polymer blends, used as nutritives and in feed compositions, and used in combination with a pharmaceutical or nutritive.
Claims34
A homopolymer, wherein the homopolymer comprises a repeat unit comprising Formula (I) and having an average molecular weight above about 800 Da, the repeat unit comprising Formula (I):
- wherein,
- R2, R4, and R5 are independently chosen from hydrogen, hydrocarbyl, and substituted hydrocarbyl;
- R6 is chosen from hydrogen, hydrocarbyl, and substituted hydrocarbyl;
- R7 is optionally present, when present it is chosen from hydrogen, hydrocarbyl, and substituted hydrocarbyl;
- Z is chosen from sulfur, sulfone, sulfoxide, and selenium;
- and
- n is an integer≧1;
- provided that where n is 2 and R6 is methyl, then Z is other than sulfoxide.
A copolymer comprising a first repeat unit and at least one second repeat unit, the first repeat unit comprising Formula (I):
- wherein,
- R2, R4, and R5 are independently chosen from hydrogen, hydrocarbyl, and substituted hydrocarbyl;
- R6 is chosen from hydrogen, hydrocarbyl, and substituted hydrocarbyl;
- R7 is optionally present, when present it is chosen from hydrogen, hydrocarbyl, and substituted hydrocarbyl;
- Z is chosen from sulfur, sulfone, sulfoxide, and selenium;
- and
- n is an integer≧1;
- and at least one second repeat unit, and provided that the second repeat unit is other than a repeat unit derived from an amino acid,
- wherein the copolymer has an average molecular weight above about 800 Da.
