A heterophasic polymer composition comprises a propylene polymer phase, an ethylene polymer phase, and a compatibilizing agent. The compatibilizing agent comprises (i) at least one tertiary carbon-hydrogen bond having a bond-dissociation energy of about 380 kJ/mol or less and (ii) at least one acyclic carbon-carbon double bond. A method of making a heterophasic polyolefin polymer composition comprises the steps of (a) providing a propylene polymer phase and an ethylene polymer phase, (b) providing a compatibilizing agent, and (c) mixing the propylene polymer phase, the ethylene polymer phase and the compatibilizing agent, in the presence of free carbon radicals. The compatibilizing agent reacts with propylene polymers and ethylene polymers thereby bonding propylene polymers to ethylene polymers.

Practical Synthesis of N-(Diphenylmethyl)- and N-(1-Adamantyl)amides Directly from Aldehydes via a One-Pot Schmidt and Ritter Reaction Sequence
conventional two-step methods. Nonoxidative and noncoupling reaction conditions have been developed for the synthesis of N-(diphenylmethyl)- and N-(1-adamantyl)amide derivatives directly from aldehydes by employing the concept of a Schmidt and Ritter reaction sequence in a one-pot operation. The reagent mixture consisting of sodium azide and HBF4·OEt2 in acetic acid converts the aldehydes into their respective
N-Benzoyl-N-benzylcinnamamides 1,
N-acetyl-N-(1-benzyl)cinnamamides 3 and
N-[(1-benzyl)aminocarbonyl]-N-(1-benzyl)cinnamamides
5 have been irradiated by a high-pressure mercury lamp in the presence
of benzil in benzene at room temperature to give
3-azatricyclo[5.2.2.01,5]undeca-8,10-dien-4-ones 2, 4 and 6
with high stereoselectivity. These are the first photo[4+2]cycloadducts
of an enone and a benzene ring.
