PARTNERS CALL GENCORP<GY> RESPONSE UNPRODUCTIVE General Acquisition Co said it was disappointed by Gencorp's response to its tender offer and questioned how the company might give better value to shareholders. Gencorp earlier urged shareholders to reject a 100 dlr per share tender offer from the partnership, which includes Wagner and Brown and AFG Industries Inc. The company said it was studying financially superior alternatives. The partnership called the response inflammatory and unproductive, particularly since it had attempted to discuss the offer with Gencorp. The partnership said Gencorp failed to say how it would provide a "superior value yet they continue their attempt to prevent a satisfactory offer by failing to redeem their poison pill." Poison pills are shareholder rights plan that make takeovers more expensive. Gencorp said in its statement earlier that the date its rights will trade separately from the common stock was extended to April six from April three. It said the extension was subject to further extensions by the board and is conditioned on no person aquiring beneficial ownership of 20 pct or more of Gencorp prior to April six. General Acquisition said it is confident its offer can be completed in a timely manner using its financial arrangements. The partnership in its statement again urged management to work with it to facilitate a transaction.
