ABSTRACT:
Terpolymers of maleic anhydride, a C.sub.1 -C.sub.5 alkyl vinyl ether and a C.sub.12 -C.sub.14 alpha-olefin, and crosslinked products thereof, are provided herein for use in thickener, adhesive, sunscreen, hair spray, and waterproofing compositions. The alpha-olefin comonomer is a hydrophobic, straight chain, unsaturated hydrocarbon such as dodecene or tetradecene, which is present in the terpolymer in predetermined amounts relative to the hydrophilic maleic anhydride component, to provide a terpolymer having a suitable HLB for these applications.
