Improved reaction processes comprise reacting a mixture to form a product comprising a metal alkyl, metal oxide, or mixture thereof and then passing said product to a post-reactor heat exchanger. The improvement comprises one or more of the following:

Processes to control fouling and improve compositions

Improved reaction processes comprise reacting a mixture to form a product comprising a metal alkyl, metal oxide, or mixture thereof and then passing said product to a post-reactor heat exchanger. The improvement comprises one or more of the following: (1) reacting said metal alkyl compound with an acid to produce a soluble metal ester; or (2) adding an ionic surfactant; or (3) adding a mixture comprising an antioxidant to the product under conditions sufficient to avoid formation of significant amounts of insoluble metal or metal compounds derived from said metal alkyl compound; or (4) purging said post-reactor heat exchanger with an inert gas under conditions to remove metal oxide from the post-reactor heat exchanger.

An adhesive composition comprising a copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and C&#x3b1;-olefins, the copolymer having (i) a content of units derived from propylene of greater than about 50 mole percent, (ii) a Brookfield viscosity at 190 C from about 50 to about 100,000 cP, (iii) an MWD from about 1.5 to about 15, and (iv) containing less than about 50 ppm residual catalyst metal.

Polypropylene-based adhesive compositions

The present invention relates to compositions and processes of making and using interpolymers having a controlled molecular weight distribution. Multilayer films and film layers derived from novel ethylene/&#x3b1;-olefin interpolymers are also disclosed.

Interpolymers suitable for multilayer films

Embodiments of the invention provide a class of propylene/&#x3b1;-olefin block interpolymers. The propylene/&#x3b1;-olefin interpolymers are characterized by an average block index, ABI, which is greater than zero and up to about 1.0 and a molecular weight distribution, M/M, greater than about 1.3. Preferably, the block index is from about 0.2 to about 1. In addition or alternatively, the block propylene/&#x3b1;-olefin interpolymer is characterized by having at least one fraction obtained by Temperature Rising Elution Fractionation ('TREF'), wherein the fraction has a block index greater than about 0.3 and up to about 1.0 and the propylene/&#x3b1;-olefin interpolymer has a molecular weight distribution, M/M, greater than about 1.3.
