Embodiment 1-6

[0122] decomplexer

[0123] As shown in Table IV, dicarboxylic acids were used as decomplexers.

[0124] Initiator component

[0125] Dissolve 1.52 g of triethylborane:hexanediamine complex (TEB-HMDA) in a 2:1 molar ratio in 3.48 g of trimethylolpropane tris(3-(2-methylaziridine) ) propionate (available from Zeneca Resins; Wilmington, MA under the tradename CROSSLINKER CX-100) (hereinafter referred to as "CX-100").

[0126] polymerizable composition

[0127] In each example, a slurry containing 10.00 grams of a core-shell toughening agent (available from GE Specialty Chemicals; Parkersburg, WV, under the trade name BLENDEX 360) and a decomplexing agent was dissolved in tetrahydrofurfuryl methacrylate (THFMA) The solution in (purchased from Aldrich Chemical Co.; Milwaukee, WI) was placed at 70°C for 3 hours. After the resulting opaque dispersion was allowed to cool, vigorous shearing was performed with the serrated paddle of a laboratory disperser (available from Premier Mi...

Embodiment 7-15

[0135] The polymerizable composition and initiator components were prepared using the materials described in Example 2, except that the amounts of the components were varied.

[0136] implement

[0137] These examples show excellent adhesion properties on HDPE and PP.

Embodiment 16-19

[0139] decomplexer

[0140] Carboxylic acid esters (Examples 16-17) and / or dicarboxylic acids (Examples 18-19) were used as decomplexers. Carboxylic acid esters are prepared as follows:

[0141] Preparation of 1,2-ethylene glycol dimaleate decomplexer

[0142] Under nitrogen and stirring, 15.50 grams (0.25 moles) of ethylene glycol (available from JT Baker; Phillipsburg, NJ), 49.00 grams (0.50 moles) of maleic anhydride (available from Aldrich Chemical Co.; Milwaukee, WI) and 0.04 moles of g benzyltriethylammonium bromide (available from Aldrich Chemical Co.; Milwaukee, WI) was mixed and heated to form a clear, colorless solution. After the solution was held at 70°C for 22 hours, it was allowed to cool to room temperature (ie, 22-25°C). The product contained 86 mole % 1,2-ethylene glycol dimaleate, 12 mole % 2-hydroxyethyl maleate and 2 mole % residual ethylene glycol as determined by proton NMR spectroscopy. This product is hereinafter referred to as "dimaleate".

Abstract

Initiator systems of the present invention include both a complexed initiator and a carboxylic acid decomplexer. For example, dicarboxylic acid decomplexer, carboxylic acide ester desomplexers, and monocarboxylic acid decomplexers (perferably those comprising an alkyl group having at least nine carbon atoms for low odor compositions) are useful in the present invention.

Description

Field of Invention [0001] The present invention generally relates to systems capable of initiating polymerization reactions. In particular, the present invention relates to initiator systems containing (1) a complexing initiator and (2) a decomplexing agent. The present invention also relates to the use of these systems in the polymerization of initiators, kits, adhesive compositions, polymeric compositions prepared therefrom, coated substrates prepared therefrom, and adhesive articles prepared therefrom and methods of making such bonded articles. Background of the Invention [0002] Systems for initiating polymerization of monomers to prepare adhesive compositions are known in the art. U.S. Patents 5,106,928, 5,286,821 and 5,310,835 to Skoultchi et al. describe, for example, two-component initiator systems for initiating the polymerization of acrylic monomers. The first component of the two-component system includes a stabilized organoborane·amine complex, and the second...
