Abstract
The present application relates to a thermoplastic graft copolymer including one or more thermoplastic polymers of formula (I): and a branched chain thermoplastic polymer of formula (II): where R1, R2, R3, R4, R4′, AETAG, a, b, c, d, and e are as described herein. Also disclosed is the process for preparing the thermoplastic copolymer and its uses.
Claims27
A thermoplastic graft copolymer comprising:
- one or more thermoplastic polymers of formula I:
- and
- a branched chain thermoplastic polymer of formula II:
- wherein:
- R1 is independently selected at each occurrence thereof from the group consisting of H and methyl;
- R2 is independently selected at each occurrence thereof from the group consisting of H, OH, halogen, —COOR5, C1-C23 alkyl, and benzyl, wherein the C1-C23 alkyl can be optionally substituted with an aryl, heteroaryl, or heterocyclyl;
- R3 is independently selected at each occurrence thereof from the group consisting of C1-C23 alkylene, arylene, and heteroarylene;
- R4 and R4′ are independently selected at each occurrence thereof from the group consisting of C1-C23 alkyl and benzyl, wherein the C1-C23 alkyl can be optionally substituted with an aryl, heteroaryl, heterocyclyl, carboxylic acid, oxirane, ester, thioester, or carbonotrithioate;
- R5 is independently selected at each occurrence thereof from the group consisting of H and C1-10 alkyl;
- AETAG is a (meth)acrylated epoxidized triacryl glyceride;
- a and b represent number average degrees of polymerization for repeat units of formula I that are distributed throughout the polymer chain in a statistically defined manner;
- a and b range from 0 to 100,000, wherein a+b ranges from 100 to 200,000;
- c, d, and e represent number average degrees of polymerization for repeat units of formula II that are distributed throughout the polymer chain in a statistically defined manner;
- c ranges from 100 to 100,000;
- and
- d and e range from 0 to 100,000, wherein the thermoplastic polymer of formula I is grafted to the thermoplastic polymer of formula II.
