Abstract
A polyolefin additive comprising chlorinated polyolefin grafted with an alkyl (meth)acrylate, wherein the alkyl has greater than 10 carbon atoms is provided. Further provided are a method for improving the sag resistance of polyolefins and sag resistant polyolefins.
Claims18
A polyolefin composition comprising one or more polyolefins and from 1 to 5 percent by weight of a polyolefin additive comprising chlorinated polyolefin grafted with an alkyl (meth)acrylate, wherein the alkyl has greater than 10 carbon atoms and wherein the alkyl of the alkyl (meth)acrylate is selected from the group consisting of stearyl, lauryl, and combinations thereof.
(canceled)
A method of improving the sag resistance of an olefin-based polymer comprising:
- adding from 1 to 5 wt % chlorinated polyolefin grafted with an alkyl (meth)acrylate to one or more polyolefins, wherein the alkyl of the alkyl (meth)acrylate is selected from the group consisting of stearyl, lauryl, and combinations thereof.
(canceled)
A sag resistant polyolefin composition comprising:
- one or more polyolefins;
- and
- from 1 to 5 wt % chlorinated polyolefin grafted with an alkyl (meth)acrylate, wherein the alkyl has greater than 10 carbon atoms, and wherein the alkyl of the alkyl (meth)acrylate is selected from the group consisting of stearyl, lauryl, and combinations thereof.
