Abstract
A pressure sensitive adhesive which is prepared by emulsion polymerizing an ethylenically unsaturated monomer and 0.01 to 2 pphm of a sterically hindered alkoxylated silane monomer. The silane crosslinks during film formation to provide the adhesive with increased shear strength without the disadvantage of decreased loop tack. The sterically hindered alkoxylated silane monomer has the structure R —Si—(OR ) (R ) wherein R is selected from the group consisting of an alkylene, arylene, and aralkylene group; R is independently a sterically hindered alkyl group having 3 to 10 carbon atoms in a straight or branched chain configuration; R is a monovalent alkyl group having 1 to 10 carbon atoms; and n is an integer of from 1 to 3.
