Abstract
The present invention relates generally to compositions prepared by polymerizing vinyl neo C9-C13 carboxylic acid esters. Such compositions include latex compositions that are formed by polymerizing vinyl neo C9-C13 carboxylic acid esters with ethylenically unsaturated comonomers such as acrylic acid esters and vinyl acetate. The polymer compositions of the present invention are particularly suitable for use in applications such as architectural (both interior and exterior), direct-to-metal and marine coatings and transportation maintenance applications.
Claims14
A polymer prepared by polymerizing a monomer mixture comprising a multi-isomer mixture of vinyl neo C9-C13 carboxylic acid esters containing at least 25 wt % vinyl neo C12 carboxylic acid esters, wherein said vinyl neo C9-C13 carboxylic acid esters are represented by the formula:
- wherein R1, R2 and R3 are independently hydrocarbyl groups each having from 1 to 10 carbon atoms, R1R2R3C′— has a neo structure about the C′ atom, and that R1+R2+R3=from 7 to 11 carbon atoms.
A composition comprising:
- (a) a first polymer prepared by polymerizing monomer mixture comprising a multi-isomer mixture of vinyl neo C9-C13 carboxylic acid esters containing at least 25 wt % vinyl neo C12 carboxylic acid esters, wherein said vinyl neo C9-C13 carboxylic acid esters are represented by the formula:
- wherein R1, R2 and R3 are independently hydrocarbyl groups each having from 1 to 10 carbon atoms, R1R2R3C′— has a neo structure about the C′ atom, and that R1+R2+R3=from 7 to 11 carbon atoms;
- and
- an ethylenically unsaturated comonomer;
- and
- (b) a second polymer prepared by copolymerizing a first acrylic comonomer and a second acrylic comonomer.
