Oct 24 (Reuters) - Chemical company PolyOne Corp struck a $246 million deal to buy plastic products maker Spartech Corp, a maker of bulletproof barriers and aircraft cabin windows, to enter new markets.

The deal represents a premium of 56 percent to Spartech's Tuesday close of $5.14 on the New York Stock Exchange, yet the shares of both companies jumped.

PolyOne stock rose as much as 9 percent to an all-time high of $18.32 on the New York Stock Exchange while Spartech shares lept 65 percent to a 20-month high of $8.48.

While well above the $8 offer price for stock-and-cash deal based on Tuesday's close, the gain for Spartech reflected the rise in PolyOne shares.

Piper Jaffray analyst Mike Ritzenthaler said PolyOne was getting Spartech for a ``relatively inexpensive price.''

``(The deal) was not more than 7.5 times trailing earnings before interest, taxes, depreciation, and amortization (EBITDA), which is pretty low for a specialty chemicals company, he said.

Spartech stockholders will receive $2.67 in cash and 0.3167 PolyOne shares for each share held, or $8 per share based on PolyOne's Tuesday close of $16.84. The deal value is based on Spartech's 30.79 million shares outstanding as of Sept. 1, according to Thomson Reuters data.

PolyOne said it expects the buyout to add to earnings in the first year, excluding acquisition-related costs and charges. The company said the deal will eventually add 50 cents to earnings per share.

The deal, expected to close in the first quarter of 2013, values Spartech at $393 million, including assumption of $142 million in debt, the companies said.

Along with its aerospace and security products, Spartech makes consumer and medical packaging products. It makes plastic sheet, specialty film laminates, specialty plastic alloys, color concentrates and blended resin compounds and has annual revenues of about $1.2 billion.

PolyOne will finance the deal with cash on hand and new long-term debt.

Ritzenthaler said PolyOne was likely to make at least one more small acquisition this year.

''Historically, Polyone's organic growth has been in low single digits. It has been important for PolyOne to make these bolt-on acquisitions`` he said.

PolyOne acquired ColorMatrix, manufacturer of colorants and other additives for plastics last October. The deal added about 2 to 3 cents to earnings per share in 2012.

Bank of America Merrill Lynch, Moelis & Co, KeyBanc Capital Markets and Jones Day advised PolyOne on the deal, while Barclays and K&L Gates were Spartech's advisers.

PolyOne posted a better-than-expected profit for the third time this year, helped by an improved product mix.

Shares in PolyOne eased back from their high to trade at $18.09 by midday on the NYSE while Spartech traded at $8.26.
