Abstract: A glass run capable of being readily attached to corner parts of a door frame of a door of a motor vehicle such that an end edge of a corner cover of the glass run can be securely engaged with an end of a corner piece. A corner cover adapted to cover a vehicle-exterior surface of the corner piece like an arcuate configuration is formed in a corner section of the glass run. An arcuate end edge of the corner cover defines a corner cover lip for contacting an end of the corner piece, and a corner cover engaging wall is formed in the corner cover so as to protrude inwardly from a vehicle-interior surface of the corner cover lip. The corner cover engaging wall and the corner cover lip define an engaging groove, and a plurality of corner cover inclination ribs are formed so as to respectively have an inclined surface connecting the corner cover engaging wall and the vehicle-interior surface of the corner cover lip.

Abstract: A polymerization initiator composition, comprising an azobisamidine salt represented by the general formula (1) ##STR1## wherein R.sup.1 and R.sup.2 independently represent an alkyl group or a cycloalkyl group, providing that R.sup.1 and R.sup.2 may together form an aliphatic ring, and Y represents --C(.dbd.NR.sup.3)--NH--R.sup.4 or a guanyl group represented by the formula (2) ##STR2## wherein R.sup.3 and R.sup.4 independently represent a hydrogen atom, an alkyl group, a substituted alkyl group, a cycloalkyl group, an allyl group, a phenyl group, or a substituted phenyl group, R.sup.5 represents a lower alkylene group optionally containing a substituent group, and R.sup.6 represents a hydrogen atom or a hydroxyalkyl group, and X represents a chlorine atom, a bromine atom, or a CH.sub.3 COO-- group, and a hydrophilic organic compound.

Abstract: A method for the production of an .alpha.-aryl-alkanoic acid represented by the general formula II: ##STR1## wherein R.sup.3 stands for a hydrogen atom or an alkyl group and Ar for an aromatic residue, characterized by subjecting an .alpha.-haloalkyl-aryl ketal represented by the general formula I: ##STR2## wherein Ar has the same meaning as defined above, R.sup.1 and R.sup.2 independently stand for an alkyl group and embrace the case wherein they jointly form a cyclic acetal, R.sup.3 has the same meaning as defined above, and X stands for a halogen atom to a rearrangement reaction in the presence of at least one zinc compound selected from the group consisting of oxide, hydroxide, sulfide, carbonate, and basic carbonate of zinc and subsequently hydrolyzing the product of said rearrangement reaction.
