Patent number: 5225470Abstract: Acrylic hot melt pressure sensitive adhesive compositions having a good balance of tack, peel and creep resistance at ambient temperature combined with optical clarity and desirable melt viscosity at elevated temperatures are prepared by copolymerizing acrylic and methacrylic alkyl esters of a non-tertiary alcohol or optionally acids with polymerizable poly methacrylate based macromonomers. The resulting acrylic copolymer has a graft or comb structure in which the acrylic backbone has a low Tg and the pendant macromonomer side chains have a Tg above room temperature. Compounding those acrylic copolymers with tackifiers and plasticizers dramatically improves the balance of pressure sensitive adhesive properties while lowering melt viscosity into a desirable range. The invention provides significant property enhancements even for acrylic copolymers having poor initial peel and shear adhesive properties.Type: GrantFiled: February 22, 1991Date of Patent: July 6, 1993Assignee: Monssanto CompanyInventor: Paul A. Mancinelli

Patent number: 4678837Abstract: An alternate procedure for preparing multilithium initiators using DVB has been developed in order to achieve better control over the specific number of anionic sites per initiator molecule and to prepare star-block copolymers having a pre-determined number of branches. The process consists of 3 distinct steps; oligomerization, activation and polymer growth. The initial step involves the oligomerization of DVB yielding a mini-block having a predetermined number of pendant vinyl groups using a monofunctional initiator such as polystyryllithium. This is quickly followed by activation of the pendant vinyl groups using s-butyllithium prior to polymer growth.Type: GrantFiled: August 23, 1985Date of Patent: July 7, 1987Assignee: Atlantic Richfield CompanyInventor: Paul A. Mancinelli

Patent number: 4640958Abstract: A new coupling agent has been disclosed which is acryloyl chloride. This coupling agent undergoes anionic polymerization through the acrylate unsaturation rather than anionic attack at the acid chloride.Type: GrantFiled: August 21, 1985Date of Patent: February 3, 1987Assignee: Atlantic Richfield CompanyInventor: Paul A. Mancinelli

Patent number: 4567239Abstract: The alkyllithium initiated preparation of terminally functional polymers in high yield is accomplished by first capping a macromolecular polymer with an alkylene sulfide prior to terminating the molecule with a halogenated compound containing a polymerizable moiety. The resulting macromolecular monomers are useful in the preparation of graft copolymers by copolymerizing the macromolecular monomers with monomers copolymerizable therewith.Type: GrantFiled: June 15, 1984Date of Patent: January 28, 1986Assignee: Atlantic Richfield CompanyInventor: Paul A. Mancinelli

Patent number: 4503188Abstract: A new class of multi-ester coupling agents has been disclosed which have the general formula, (CH.sub.2 .dbd.CH-CO.sub.2).sub.n X, where X is a radical from a polyhydroxy compound having 2 to 6 hydroxyl groups, and n is an integer equal to the number of hydroxy groups in the polyhydroxy compound. These coupling agents undergo anionic polymerization through the acrylate unsaturation rather than anionic attack at the ester linkage.Type: GrantFiled: June 20, 1983Date of Patent: March 5, 1985Assignee: Atlantic Richfield CompanyInventor: Paul A.
