Appl. No.:

7/738009

Inventors:

Andrew J. Swartz - Newtown PA

Assignee:

Rohm and Haas Company - Philadelphia PA

International Classification:

C08K 506

US Classification:

524366

Abstract:

An aqueous aerosol coating composition comprising a blend of neutralized acrylic dispersible polymer having a relatively high Tg, high acid number and low molecular weight, with a drying oil-modified, low molecular weight copolymer in a water-based carrier and propellant system which comprises dimethyl ether, water and a water-soluble organic solvent. Compositions containing the blend of this invention produce polymer coatings that possess improved drying time without adversely effecting other physical properties.

Appl. No.:

15/830676

Inventors:

- Collegeville PA, US
Arnold S. Brownell - Lansdale PA, US
Andrew Swartz - Fleetwood PA, US

International Classification:

C08J 3/05
C08L 33/14
C08F 30/02

Abstract:

The present invention provides a composition comprising 1) an aqueous dispersion of polymer particles having a core-shell morphology wherein the core protuberates from the shell; wherein the core comprises from 5 to 90 weight percent structural units of a fluoroalkylated monomer, and 2) less than 0.09 weight percent structural units of a phosphorus acid monomer; and wherein the shell comprises from 0.1 to 5 weight percent of itaconic acid or a phosphorus acid monomer, based on the weight of the shell. The present invention addresses a need in the art by providing a way of selectively concentrating fluoroalkyl functionality into polymer particles with acorn morphology, thereby providing an improvement in dirt pick-up resistance of the subsequent coating.
