Abstract
The present invention provides a highly storage-stable silicone-grafted vinyl copolymer emulsion composition that can produce films and coatings that are highly water repellent, water resistant, adhesive, and printable, the composition including (A) vinyl monomer, (B) carbosiloxane dendrimer that contains a radically polymerizable organic group, (C) surfactant, and (D) radical polymerization initiator.
Claims4
A silicone-grafted vinyl copolymer emulsion composition produced by the emulsion polymerization of components comprising
- (A) a vinyl monomer;
- (B) a carbosiloxane dendrimer that contains a radically polymerizable organic group of the formula
- wherein Y is a radically polymerizable organic group, R1 is C1 to C10 alkyl or aryl, and X1 is the silylalkyl group with the following formula when i=1:
- wherein R1 is defined as above;
- R2 is C2 to C10 alkylene;
- R3 is C1 to C10 alkyl;
- Xi+1 is selected from the group consisting of hydrogen, C1 to C10 alkyl, aryl, and the above-defined silylalkyl group;
- i is an integer of from 1 to 10 that specifies the generation of said silylalkyl group;
- and ai is an integer from 0 to 3, wherein the weight ratio of (A):(B) is from about 0:100 to 99.9:0.1;
- (C) a radically polymerizable surfactant, at from 0.01 to 20 weight parts for each 100 weight parts of the total of components (A) and (B);
- and
- (D) a radical polymerization initiator, at from 0.01 to 20 weight parts for each 100 weight parts of the total of components (A) and (B).
