DEFINITION

Classification: 526/124.3

(under subclass 124.2) Subject matter wherein an additional specified material is present (i.e., there are four or more specified materials present).

(1) Note. This subclass provides, inter alia, for the combination of TiCl4, MgCl2, Al(CH3)3 and an additional specified material such as Al(C2H5)3, PCl3 or alcohol.

(2) Note. Material such as Mgm Ti(OR) mXp[ED]q wherein R is hydrocarbon, X is halogen and ED is a specified material such as a carboxylic acid ester will be considered to represent a mixture of specified materials rather than a unitary compound. In this particular mixture, ED represents the additional specified material which satisfies the requirement of this subclass.

(3) Note. For purpose of this and indented subclasses, materials such as MgCl2 deg.2H2O are generally regarded as constituting two specified materials (i.e.,

MgCl2 and H2O). See Search This Class, Subclass, infra.

124.4, for MgCLI2.2H2O considered as a single specified material. SEE OR SEARCH CLASS
