Abstract
The invention is directed to an nanocomposite material and products produced from the nanocomposite material. This invention is also directed to a process for preparing a polymer-clay nanocomposite comprising the steps of (i) forming a concetrate comprising a layered clay material with a matrix polymer-compatible functionalized oligomer or polymer, and (ii) melt compounding the concentrate with a melt-processible matrix polymer to produce a polymer-clay nanocomposite.
Claims55
A polymer-clay nanocomposite comprising:
- (i) a melt-processible matrix polymer,
- (ii) a layered clay material, and
- (iii) a matrix polymer-compatible oligomer or polymer having an onium functional group bonded thereto.
A polymer-clay nanocomposite comprising:
- (i) a melt-processible matrix polymer, and incorporated therein
- (ii) a concentrate comprising a layered clay material and a matrix polymer-compatible oligomer or polymer having an onium functional group bonded thereto.
A process for preparing polymer-clay nanocomposite comprising the steps of:
- (i) forming a concentrate comprising a layered clay material and an oligomer or polymer having an onium functional group bonded thereto, and
- (ii) melt mixing the concentrate with a melt-processible matrix polymer to form a polymer-clay nanocomposite.
A process for preparing a polymer-clay nanocomposite comprising:
- melt mixing a layered clay material, an oligomer or polymer having an onium functional group bonded thereto, and a melt-processible matrix polymer to form a polymer-clay nanocomposite material.
