It is possible to buy bitcoin with Paypal, in indirect way. Most sellers are reluctant to offer a bitcoin-through-PayPal alternative, because they might never see their money.
Bitcoin buyers can get a chargeback. They may use their PayPal accounts, they get their bitcoins, then they falsely claim to PayPal or their credit card company that they did not receive any bitcoins, and PayPal stands with the fraudulent bitcoin buyer. This is why most established bitcoin exchanges do not support funding via PayPal.
Bitcoin sellers face other risks, too. Users can hack accounts and misuse them; when PayPal notices this, they will perform a chargeback. Moreover, PayPal and bitcoin are competing virtual currencies, so some bitcoin users assume that PayPal frowns upon bitcoin. According to them, if PayPal notices that you deal with bitcoins, they will delete your PayPal account and freeze your balance. However, in September 2014, PayPal announced that it would cooperate with three major bitcoin player, Coinbase, BitPay, and GoCoin. These days, a PayPal web app, PayPal Payments Hub, allows you to add bitcoin payments.
