Abstract
Official abstract text for this publication.
A lactide-functionalized polymer is represented by the following formula: wherein R is a hydrogen atom or a methyl group, and wherein R′ is a phenyl group or C(O)OR″, wherein R″ is an alkyl group having one or more carbon atoms.
First claim
Opening claim text (preview).
What is claimed is: 1. A lactide-functionalized polymer represented by the following formula: wherein R is a hydrogen atom or a methyl group, wherein R′ is a phenyl group, wherein the variable n denotes a degree of polymerization of repeating units, and wherein the value of the variable n is greater than 1. 2. A lactide-functionalized polymer represented by the following formula: wherein the variable n denotes a degree of polymerization of repeating units, and wherein the value of the variable n is greater than 1. 3. The lactide-functionalized polymer as recited in claim 1 , wherein the lactide-functionalized polymer is represented by the following formula: wherein the variable n denotes a degree of polymerization of repeating units, and wherein the value of the variable n is sufficient to provide the lactide-functionalized polymer with a number average molecular weight M n between about 1000 and about 10,000. 4. A lactide-functionalized polymer represented by the following formula: wherein R is a hydrogen atom or a methyl group, wherein R′ is a phenyl group, wherein the variable n denotes a degree of polymerization of repeating units, and wherein the value of the variable n is sufficient to provide the lactide-functionalized polymer with a number average molecular weight M n between about 1000 and about 10,000.
